wireless internet access, pocket Age of Empires (along with a variety of other games, but pocket AOE has by far the largest WOW factor), contacts, notes, memos, schedule, ebooks (quite convenient actually), plan on putting on a dictionary, potentially might do music on it (but I have an iPod handling that mainly), plan on doing the movie thing for long trips combined with a 4GB microdrive
I just upgraded to a Toshiba E750 from my Visor Edge. The gadget factor is definitely there. The visor functioned as a great basic PDA/basic game machine, but I wanted to try something new. The larger form factor is a bit hard to get used to, but I can live with it (the Edge still is one of the smallest PDAs ever made, once a case is factored in (the Edge had a built in metal screen protector negating the need for a case)). The color screen is a definite step up, but the battery life on these new devices is nowhere near the old devices life. I could get a month of spare usage on the Edge's rechargeable. I can get a day of decent usage out of the Toshiba (but the batteries are replaceable). Both of them are smooth little devices though!
