That's actually what kind of happened to me with MP3-Players. "Mhm, I could buy an iPod Nano for ~150 or this whatever-brand with more space for ~100. Two months later I got the iPod Classic, best decision ever."
heh, that's exactly my mp3 player story. I bought a small samsung device (dude, look, it plays ogg files! it must be the best!). Less than a month later I bought an ipod nano.
