I just got my new T1 as well as the cover with included light (PRSA-CL10B).
Here's my thoughts:
The good:
- very nice GUI overall
- Create collections directly on the T1
- Buy books over wifi
- Reactive touch screen
- Good readability
- It's running Android :-)
- Google and Wikipedia search from within a book
- Very nice cover
- Different fonts built in
- You can loan books
- Good choice of font sizes
The bad:
- The time for sleep mode cannot be changed
- Only one book in the "continue reading" list
- Page buttons on the wrong side. (This is actually very annoying!)
- You cannot loan books in most countries
The ugly:
- There's no place to store the pen. Not even on the cover.
Overall I'm very happy with my T1. I'm especially glad I spent the extra 50$ (or so) for the cover. I know that other people have issues with crashes but so far my reader has not crashed while:
- reading some books
- making some notes and annotations
- buying some books via wifi in the Sony store (from Norway with our company address in the US, but what you gonna do :-) )
- syncing with Calibre
