"So small you barely feel it in your pocket."4.0 starson by PhilippeLemay
Pros: Super portable, with enough bells and whistles to keep it competitive (camera, flash, wifi, GPS, radio antenna. youtube).
Cons: Small size means a small screen, slight lag when switching between some apps, despite it's 512 MB of RAM.
Summary: I'd have to disagree with the above review, the camera is actually quite respectable (considering the price base here). You won't be filming 1080p video, for sure, but I've been using it to take pictures of cargo at work and the details and text in the picture is quite eligible. The built-in flash also acts as a great flash light (just watch out for that battery level).
The only real downer is the tiny screen 3.2 inches is small. It makes the on-screen keyboard even harder to use. And it makes reading eBooks less enjoyable. But really... when it's in your pocket it's so small and light you sometimes forget it's even there.
Good for mid-range to low-range buyers.
