It's the little things...
A fun little thing... I'm Google-ing around and it just occured to me that I'm lying in bed, wirelessly surfing, and looking at an entire page of Google results on a single screen. This Toshiba Tablet PC's screen is amazing!
Another little thing... a clean Outlook installation. It's been almost a week and I haven't had a single Outlook hang or error. They'd gotten so common on my old laptop that I was actually getting resigned to a certain level of instability. Currently, I'm running a very (for me) lean installation with only Lookout and NewsGator installed (plus Anagram which is external and Knockout for the occasional orphan Outlook process).
One final little thing... Mindjet's MindManager is utterly brilliant on a Tablet PC. A few folks I know who've been using a Tablet for some time kept trying to tell me that but you have to experience it first hand to really appreciate the potential this platform has when software is writen specifically to take advantage of its strengths.
