Ok, went to Target today, and saw both a 300 and a sony touch 600 (I think..?), and played around with both. Luckily, both were working! I had my 505 in my purse, so I took it out to compare and play around. I liked the swiping on the touch, that was pretty cool, but I definitely did notice a difference in screen clarity between the pocket and the touch. The pocket was adorable- and I just felt like I was looking at my 505ʻs little brother or sister. The screen set up was identical and the clarity seemed extremely comparable. I think if my 505 bites the dust (God forbid

), the 300 looks like the most likely replacement at this time. It looks, though, like you can only turn the pages using those buttons on the bottom? I would miss the side option....
It was sort of interesting though... the 300 at Walmart was $199. At Target, the price on the (locked) shelf was $229 and the price on the actual display was $234. Whatʻs up with that??
