@wings99: Thanks, I'd better check out the screen in a shop, maybe I'll upgrade. On a side note it's somehow very pleasing to me that your 650 won't sit unused on your shelf
If I decide to go for a PRS-T2 mine will certainly be given to someone that'll use it.
@kranenborg: Incidentally I installed PRS+ last night, just before writing my previous post. It looks promising, but don't really add all that much for me. As I'm proficient at making epubs (it's actually part of my job description) I routinely tweak my books so that they fit my preferences. I'm however embarrassed, as a Linux-head, that after all this time I didn't know that Montevista Linux was driving my reader. Thanks for that tidbit!
Thanks a lot to you both for your replies
