Congratulations on the upcoming birthday present! I do hope you get in on the free ebooks offer before it expires.
I would also be concerned about a device with multiple pixels. Mine actually has one dead pixel that I've noticed. It might have more, but they are hard to find. You need to be looking at it when it's white area around it. And even then it looks like a speck you would blow or wipe off the screen. I haven't noticed mine for months, so it's either gone or I've just tuned it out in my brain somehow.
At any rate, good luck with the purchase (and one for your wife also?) and glad to have you at MobileRead. Let us know what you think of it. The ebook Reader I mean, but any praises for MR are also quite welcome!
