对于 iOS 的每个主要新版本，有些人已经使用Beta版几个月了，有些人在最终版本可用的第二秒就更新，有些人会尽可能推迟升级。
这是最后一类应该特别阅读本文的人，因为您需要决定是否要推迟升级，或者新的花里胡哨是否值得潜在的缺点。我们从日常使用的角度评估了iPadOS ，印象深刻。(iPadOS)
外观部(The Looks Department)
在我们的 9.7 英寸 iPad Pro上，iPadOS13 给人的第一印象就是空间。在 iOS12 下，使用 iPad 感觉还是很像玩具。大(Big)而粗的图标，按比例感觉就像一个电话界面，专为单手使用而优化。与更大的 iPad 屏幕明显不匹配。
现在有足够的空间来呼吸，并且对可读性没有明显影响。最后，现代 iPad 上的大型视网膜显示屏得到了公正处理，您将花费更少的时间在屏幕之间滑动来访问您的软件。
最重要的是，最近推出的扩展坞终于有了自己的功能，为应用程序和文件夹提供了更多空间。当您向扩展坞添加更多图标时，它会改变形状，缩小图标。在我们的 iPad 型号上，我们可以容纳 16 个图标，包括停靠栏右侧的三个“最近使用的应用程序”。
有了这个房间，iPad 现在感觉就像一台“严肃”的电脑，是入门级MacBook(MacBooks)的替代品。
多任务处理(Multitasking)
到目前为止，从用户角度来看，iPadOS 带来的最大变化是改进了多任务处理。打开多个应用程序、在屏幕上拆分它们或在它们之间切换从未如此简单或更好。
多任务功能列表太长了，无法在此处一一列举，但仅针对单个应用程序的新拆分视图就值得入场。在这里，您可以在屏幕的两侧打开相同的应用程序。
这对于最近的文件(Files)应用程序非常有用，因为您可以通过拖动它们来快速在文件夹之间复制文件。与最初的分屏功能的发布一样，目前支持此功能的主要是原生Apple应用程序，但您可以放心，第三方开发人员会很快赶上。
唯一的缺点是你必须学习一套新的手势和惯例。我们花了一段时间才弄清楚如何在升级后恢复分屏功能。特别是因为没有以前没有的点击并按住弹出菜单。
然而，一旦你掌握了它的窍门，你会想知道你以前是如何使用 iPad 工作的。
表现(Performance)
苹果(Apple)经常被指责用新的 iOS 版本让旧设备陷入困境。对于早期的 iPad 世代来说，这确实有点真实。到最后一次支持操作系统更新时，像第三代 iPad 这样的设备非常落后，几乎无法使用。
不过，苹果(Apple)承诺每台支持 iOS13 家族的设备都会有性能提升。您将获得多少性能取决于具体型号，但至少没有人应该以较慢的设备结束。
有趣的是，使用我们自己的 iPad Pro，老实说似乎没有太大区别。虽然应用程序的启动速度可能更快，但您可能需要使用秒表来衡量改进情况。
这款 iPad 在 iOS12 下已经非常活泼，这反而削弱了对性能的任何看法。基本上(Basically)，您似乎不应该以一种或另一种方式考虑 iPadOS 的性能。
控制器支持(Controller Support)
随着Apple Arcade的发布，iPadOS 和整个 iOS13 系列现在都原生支持Xbox One 蓝牙控制器（不是(Xbox One Bluetooth)Windows机器上需要加密狗的控制器）和市场上大多数索尼 PS4 DualShock 4(Sony PS4 DualShock 4)控制器。除了一些早期的单位。
任何使用MFi控制器的游戏都可以立即兼容，我们在连接Xbox One或PS4控制器时遇到了绝对零问题。
支持手柄的Apple Arcade(Apple Arcade)游戏已经准备好PS4按钮提示，但如果您正在玩尚未更新的MFi手柄游戏，您仍然会收到(MFi)Xbox提示。因此，如果您更喜欢索尼(Sony)游戏手柄，希望您最喜欢的游戏的开发者能够更新它。
我们的 Xbox 控制器确实遇到了一个相当大的问题。左侧模拟摇杆似乎有一些轻微的漂移；当摇杆居中时，它仍然会接收少量输入。在游戏中，即使不使用控制器，也会显示为角色向左走，使一切无法玩。我们确认问题实际上出在控制器上，但这是一个相当普遍的问题。
它没有出现在我们的Windows机器上，因为您可以使用内置实用程序校准任何控制器。我们在 iPadOS 中找不到任何操作系统级别的(OS-level)控制器校准实用程序，这意味着如果您的控制器确实出现轻微漂移，您必须比在其他允许校准的平台上更快地修复或更换它。
然而，我们的PS4控制器就像一个魅力一样工作，并且在 iPad 上通过适当的控制玩游戏是一个启示。对于可能已经拥有这些控制器之一的 iOS 游戏玩家来说，iPadOS 几乎弥补了剥夺我们开发者放弃的游戏的32 位清除(32-bit purge)。
最终判决(The Final Verdict)
我们想不出很多避免升级到 iPadOS 的理由。这是迄今为止对这款轻薄计算设备所能做的最全面的改造。
自从 iPad 首次实现分屏多任务处理以来，它的生产力并没有得到如此大的提升。在一个包含超极本和Microsoft Surface的世界里，iPad 绝对需要大修，作为一款中低档生产力设备，iPadOS 终于让 iPad 成为笔记本电脑的可行替代品。
如果您是 iOS 游戏玩家，iPadOS 是轻而易举的事。Apple Arcade和控制器支持确保了这一点。如果您是使用 iPad 进行任何形式的工作或想要认真尝试的人，iPadOS 是必不可少的。
如果您只使用 iPad 浏览网页、观看Netflix和阅读电子书，您几乎不会注意到任何差异。在这种情况下，没有令人信服的理由立即更新。
话虽如此，iOS13 已经收到了三个主要补丁(three major patches)，因此苹果(Apple)显然致力于消除任何应该出现的皱纹。这意味着我们当中较为谨慎的人可能无需等待很长时间，iPadOS 就成为一个安全的赌注。
Apple iPadOS Review: First Impressions
With every major new release of iOS, there are those who havе already been using the Betа version for months, those that update the very second the finаl release becomes available аnd those who will put off the upgrade aѕ long as рossible.
It’s the last category of people that should read this article in particular, because you need to decide whether you want to hold off on upgrading or if the new bells and whistles are worth the potential downsides. We evaluated iPadOS from a daily use point of view and came away impressed.
The Looks Department
On our 9.7” iPad Pro, the immediate impression you get from iPadOS13 is one of space. Under iOS12, using an iPad still felt very much like a toy. Big, chunky icons that felt proportionally like a phone interface, optimized for one-handed use. An obvious mismatch for the much larger iPad screen.
Now there’s plenty of room to breathe and no noticeable impact on readability. Finally, the massive retina display on modern iPads is done justice and you’ll spend less time swiping between screens to get to your software.
Most importantly, the recently-introduced dock finally comes into its own, with more space for apps and folders. As you add more icons to the dock it changes shape, shrinking the icons down. On our iPad model we could fit 16 icons, including the three “recent apps” on the right of the dock split.
With all this room, the iPad now feels like a “serious” computer and an alternative to entry-level MacBooks.
Multitasking
By far the biggest change iPadOS brings from a user perspective is improved multitasking. Opening multiple apps, splitting them across the screen or switching between them has never been easier or better.
The list of multitasking features is too long to go through here, but the new split view for single apps alone is worth the price of admission. This is where you can open the same app on both sides of the screen.
This is super useful for the fairly recent Files app, because you can quickly copy files between folders by dragging them across. As with the release of the original split screen feature, it’s mainly native Apple apps that support this feature right now, but you can be assured that third-party developers will catch on quickly.
The only downside is that you’ll have to learn a new set of gestures and conventions. It took us a while to figure out how to get split screen functionality back after upgrading. Especially since there is not a tap-and-hold popup menu that wasn’t there before.
Once you get the hang of it, however, you’ll wonder how you ever used your iPad for work before.
Performance
Apple is often accused of bogging down older devices with new iOS versions. With early iPad generations, this does feel somewhat true. By its last support OS update devices like the 3rd-generation iPad were so laggy they were barely usable.
However, Apple promised that there will be a performance improvement for every device that supports the iOS13 family. How much more performance you’ll get depends on the specific model, but at the very least no one should end up with a slower device.
Anecdotally, with our own iPad Pro, there honestly doesn’t seem to be much difference. While apps might be launching more quickly, you might need to use a stopwatch to measure the improvement.
This iPad was already incredibly snappy under iOS12, which rather dampens any perception of performance. Basically, it doesn’t seem like you should think about performance one way or another with iPadOS.
Controller Support
Timed alongside the release of Apple Arcade, iPadOS and the entire iOS13 family now have native support for the Xbox One Bluetooth controller (not the one requiring a dongle on Windows machines) and most of the Sony PS4 DualShock 4 controllers on the market. With the exception of a few early units.
Any game that works with MFi controllers is immediately compatible and we had absolutely zero issues connecting either the Xbox One or PS4 controllers.
Apple Arcade games that support controllers already have PS4 button prompts ready to go, but if you are playing MFi controller games that have not been updated, you’ll still get the Xbox prompts. So here’s hoping the developer of your favorite game will update it if you prefer the Sony gamepad.
We did run into one rather major issue with our Xbox controller. It seems to have some mild drift on the left analog stick; when the stick is centered, it still picks up a slight amount of input. In-game, this is exhibited as the character walking to the left even when the controller is not being used, making everything unplayable. We confirmed that the problem is in fact with the controller, but this is a fairly common issue.
It did not show up on our Windows machine, since you can calibrate any controller using the built-in utility. We were unable to find any OS-level controller calibration utility in iPadOS, which means that if your controller does develop mild drift, you’ll have to repair or replace it much sooner than you would on other platforms that allow for calibration.
Our PS4 controller worked like a charm however and playing games on the iPad with proper controls is a revelation. For iOS gamers, who probably already have one of these controllers laying around, iPadOS almost makes up for the great 32-bit purge that robbed us of games developers had abandoned.
The Final Verdict
We can’t think of many reasons to avoid upgrading to iPadOS. This is by far the most comprehensive overhaul of what this thin and light computing device can do.
The iPad has not received such a productivity boost since it first got split-screen multitasking. In a world that contains ultrabooks and the Microsoft Surface, the iPad absolutely needed an overhaul and as a light-to-moderate productivity device, iPadOS finally makes the iPad a viable replacement for a laptop.
If you are an iOS gamer, iPadOS is a no-brainer. Apple Arcade and controller support clinches it. If you are someone who uses your iPad for any sort of productivity or wants to give it a serious go, iPadOS is essential.
If you only use your iPad to browse the web, watch Netflix and read ebooks, you’ll barely notice any difference at all. In which case, there’s no compelling reason to update immediately.
That being said, iOS13 has already received three major patches, so Apple is clearly dedicated to ironing out any wrinkles that should appear. This means the more cautious among us might not have to wait long before iPadOS is a safe bet.
