Chromebook, Netbook, iPad: Which would you rather spend $500 on?

esterday's formal introduction of Chromebooks marked yet another category of portable computing gadget in a landscape that's starting to feel overrun.

For $499, the Samsung Series 5 Chromebook has its work cut out for it--namely, because tablets and "high-end" 11- and 12-inch laptops and Netbooks (some with faster processors) have already occupied the same landscape.

It's a question we've been pondering for a while now, writ again: what truly constitutes the perfect small-screen portable? Suddenly, instead of one or two OSes to consider, there are four: Windows 7, Apple's iOS, and Google's Android and Chrome.

While the high end of the computer spectrum remains relatively stable (desktops, laptops), the increasingly fertile (or, perhaps, unstable) ground between laptops and smartphones has bred a variety of tech forms that all, in some way, are portable. Options have never been more diverse, or confusing.

Which one would you rather spend about $500 on?
