Tom's Hardware published a review of Apple's iPad 2

I bought the 16 GB WiFi-equipped iPad when it first came out. Like many others, I returned it a month later.

As much as I liked Apple’s latest gizmo, I just couldn’t find a way to consistently use it. Sure, the iPad was more portable than a notebook, but it doesn’t run OS X. Instead, Apple decided that the iPad should run on iOS, the mobile version of its desktop operating system.

And therein lies my problem. OS X applications don't run on iOS. That means I can't run Microsoft Office or Adobe Photoshop, the two tools that I need to stay productive. There are applications in Apple’s App Store that serve as quasi-substitutes, but paying more for a program that I already have (with fewer functions) isn’t what I need.

Whatever I gained in portability, I lost in productivity. The iPad is a solid content consumption device; it's not nearly as suited to creation. If you want to be productive, you still need a computer.
