Apple iPad 2
The undisputed king of them all, y’all. The Apple iPad 2 has been the most popular tablet on the market and the dual-core processor inside gives it enough horsepower to handle many resource-intense tasks like photo editing or music editing. The tablet’s thin and light design make it an eye-catching computing device and the multiple cameras make it easy to share photos or make video calls with FaceTime. The app ecosystem is the best in the business, as many developers are creating apps that specifically take advantage of the tablet form factor.Some of you may not like the limitations of the iPad 2 and its operating system, as you won’t get any widgets on the homescreen and it’s tough to tinker with it without voiding your warranty. There are some cheaper alternatives but in general, you get what you pay for. Unless you have a very specific need with your tablet, the iPad 2 is likely the tablet of choice for you or your student.
Samsung Galaxy Tab 10.1

Unfortunately, the Android tablet app ecosystem isn’t as robust as the iOS App Store and the cameras aren’t anything special. Still, the Galaxy Tab 10.1 is probably the best tablet out there if you don’t want an iPad 2 and it could be just as good as the device if the app ecosystem got better.
Asus Transformer

As I mentioned with the Galaxy Tab 10.1, the Android app ecosystem is still kind of weak right now. Still, will a Tegra 2 chipset, nice design, a 10-inch screen, a low entry-level price and a host of flexible accessories, the Asus Transformer is a quality option for any tablet seeker.
BlackBerry PlayBook
While the larger tablets are great, there is something to be said for a 7-inch tablet because these can be far more portable and the best of the 7-inch bunch is the BlackBerry PlayBook. This dual-core tablet is powerful enough to handle nearly whatever you want, the screen is great to look at and the QNX OS is a refreshing take on mobile computing – if combines the best of webOS, iOS and Android.Unfortunately, the BlackBerry PlayBook still doesn’t have a native e-mail or calendar app, which means you’ll need a BlackBerry to fully take advantage of this tablet. The PlayBook will soon be able to run Android apps, which will really make up for the dearth of tablet apps on QNX. The 7-inch form factor also isn’t for everyone, so make sure you or your student really needs the portability.
