Yes, of course, a lot of the problems reported were software issues (and this is compounded by the fact that no hackers have turned their attention to these devices and thus you cannot install regular Android ROMs). But I was more concerned about the screen: performance, color saturation, need for backlighting for good visibility, viewing angles, etc.
