Deathmatch: User interface
It's often a throwaway comment that Apple's UIs are better than everyone else's, though it's not always true, as evidenced by the MobileMe service. But the iPad 2's iOS 4 is in fact a better-designed UI in many respects, allowing easier and faster access to the device's capabilities and information. Where the Xoom's Android 3.0 OS outshines the iPad 2 in terms of UI is through its widgets and notification capabilities, as previously mentioned.
Android users will find the Xoom's UI both familiar and strange. Gone are two standard buttons at the bottom of all Android smartphones: Search and Menu. These buttons now appear at the discretion of each application in the upper right of the screen. The standard Home and Back buttons remain at the bottom of the Xoom screen, though they use entirely different -- and ugly -- icons. These two on-screen buttons and the notification widget take up the entire bottom of the screen, shrinking the available viewing area. (On Android smartphones, these buttons are in the device rather than on-screen, and the notification widgets appear only on the home screens.) This loss of screen especially matters on the Xoom in landscape orientation, where the widescreen layout already shortens its display area uncomfortably compared to the iPad 2.
Operational UI. The Xoom doesn't suffer the excessive reliance on the Menu button as Android smartphones do. The Xoom instead uses its larger display area to make relevant controls easily accessible on-screen, as the iPad and iPhone always have.
The Android OS's Settings app can be disorienting, and the white-on-black text makes it nearly impossible to view in bright daylight. For example, there are two Wi-Fi options: Wi-Fi and Wi-Fi Settings. Tapping Wi-Fi turns off Wi-Fi -- not what I expected. To find a Wi-Fi network, you tap Wi-Fi Settings. After a while I learned the difference, but it was an unnecessary exercise. (Bluetooth is handled in the same awkward manner.) The iPad 2's iOS doesn't let you confuse turning Wi-Fi on or off with selecting a network, thanks to a single location with clearly designated controls.
The good news is that pinching and zooming, as well as autorotation as you turn the device, work equivalently on the Xoom's Android OS and iPad 2's iOS. For text entry, I find the iPad 2's on-screen keyboard to be easier to work with than the Xoom's, with clearer keys and better contextual use of extra keys, such as in the Mail application. Although I appreciate the intent behind the Xoom's use of Tab and other keys not found on the iPad 2, the result is that the keyboard is not full size in landscape orientation (the iPad 2's is) and thus difficult for touch-typing. I'm sure I'll eventually get used to it, but it remains an annoying UI decision.
Text selection and copying. The Xoom's Android OS falls short of the iPad 2's iOS in its text selection. If you're tapping away and realize you've made a mistake not caught by the autocorrect feature, such as when typing a URL, it can be difficult to move the cursor to that error's location in the text. If you tap too long, the screen is filled with the Edit Text contextual menu; it took me a while to figure out how to tap long enough to move the text-insertion cursor to a new location without opening that menu. It is true that Xoom is not as bad in this regard as the various Android smartphones I've tested.
On the iPad 2, you tap and hold where you want to insert the text cursor (sort of like using a mouse), and a magnifier appears to help you move precisely to where you want to go. You then add and delete text at that location. Plus, the controls for text selection appear, so you can use those if you'd like and not worry about a screen-filling menu getting in the way.
The winner: A tie -- although iPad fans may find the Android OS too loosey-goosey and its ever-present alerts annoying, Android fans may find the iPad a bit too rigid and disconnected from what's going on. To each his own; both work.
Deathmatch: Security and management
A long-standing strike against the Android OS is its poor security. The standard Android OS doesn't support on-device encryption, and it supports only the most basic of Exchange ActiveSync (EAS) security policies. By contrast, with the enhancements made in iOS 4, the iPad has become one of the most securable mobile devices available, second only to the RIM BlackBerry.
Google recognized that deficiency and has added on-device encryption to the Xoom's Android 3.0 OS. My only beef is that it takes an hour to encrypt the Xoom when you enable that capability (by contrast, the Motorola Atrix smartphone requires no time at all to enable encryption). Fortunately, it's a one-time activity. Also thanks to changes in Android 3.0, the Xoom now comes close to matching iOS 4's support of EAS policies, adding support for complex passwords, password expiration, and password history restrictions. iOS 4 has more security capabilities overall, but Android tablets are much more securable than Android smartphones.
Both the Xoom and the iPad 2 offer remote wipe, SSL message encryption, and timeout locks. If your Xoom is lost or stolen, you can lock or wipe it via your Google account or via Exchange. (Strangely, the Xoom doesn't come with the handy service Motorola Mobility provides its Atrix users to track a lost or stolen device and lock it or wipe its contents remotely.) Apple also supports remote lock and wipe; you even get the free Find My iPad service to track your iPad 2's location from a Web browser, iPhone, iPod Touch, or other iPad, and disable or wipe the device if you want.
The Xoom's Android OS can back up contact, calendar, and email data wirelessly to Gmail, as well as system settings and application data to Google's servers. The iPad too can back up such data to the cloud if you subscribe to Apple's $99-per-year MobileMe service. Syncing the iPad 2 to your computer's iTunes also backs up -- and encrypts, if you desire -- the data without requiring MobileMe. iTunes backs up everything: your media, your apps, their settings, their data, and most of your preferences. (iTunes can be configured for use in the enterprise, though most companies don't know that.)
The winner: The iPad 2, without question. The Xoom has brought in a key business security capability (encryption) but hasn't gone as far as needed by most businesses in its EAS support -- a surprise, given that the Motorola Mobility Atrix released around the same time has those capabilities.
