Gonna agree with you guys, the live messenger site is just too clunky and it doesn't work always. I tried using it last night and it routinely would tell me it couldn't send a message to someone while I was chatting with them; the interface is pretty bad and hard to work with on a small screen with a virtual keyboard. This needs a real app!
I'd like to see an email application as well, something real basic to read emails (pop/imap/smtp). Or have the office mobile group/windows mobile group port over Office for Zune HD and charge us a few bucks for it - I would pay.
Need a notes application too!!
