seconded!

only just got round to upgrading, and can't believe the difference with finger/thumb usage - EVERY aspect is now do-able with thumb touch, from connecting to wifi to browsing to file manager, opening pdfs etc.

have only just discovered this and haven't even had to get the stylus out at all for the last hour.

fantastic stuff, well worth the upgrade alone. anyone like me who wasn't bothering, I highly recommend it!
