So, I was going to ponder it for a while, though I kept coming back to the Sony - I like the Sony. If it read Mobi I think it would have been a done deal, but you know, trying to be a good girl and do my research and resist the urge of I want it and I want it now...
But I have been looking up Sony every day both on their website (hoping for the random price drop that was for such a limited time) and on campusi.com. Well, Amazon Marketplace had some good ones, and while I was looking at it right before my eyes someone dropped their price. (Not even sure why I went back to the page I had already looked at, because otherwise I would have missed it. Must have been meant to be.

)
The new price? $199. With expedited shipping (well, I want it NOW), $213.
For that I'll make the leap.
Thanks one and all for your advice, help, and patience with the 500 questions or so I've had. I'm sure you'll see my little confused self again puzzling over conversion and all that good stuff.
