I was wondering about the features. I'm a casual user who just wants to listen to music, surf, play games, and (maybe) read. I don't take pictures often so I could use my iPod. I'm fine with Wifi. But should I care about the screen size? Is there an internet speed difference? And what about the missing volume buttons, would that get annoying? I have about $225 and my birthdays coming up. Is it worth the investment or should I just get the Fire? For the record I don't have a job.
