This is a great news

. I hope we'll see it sold this year...
I like the fact that it's a European company

. We probably won't have to wait for the European launch

.
The open platform idea is excellent. No better way to build a community around a product. Well done.
At first glance, I like the Web site idea however I won't be certain about my positive opinion until I see it working.
PDF support... Hmmm... If that's a true support, it may be the killer feature. But I know too well that it's easier said than done... so time will tell.
All in all, it's a pretty exciting news. I love my PRS 505 but I'm not married to it so I'm allowed to keep my eyes open
