I love my TyTN!

But I've had it for a while now and I think I would like to upgrade to the TyTN II.

I need to sync with outlook (work stuff)
g-mail
light/moderate web browsing
I really like the GPS idea (because I keep getting lost!)
I don't want anything much larger than the TyTN or heavier.

Is the TyTN II a big enough upgrade for the money? or should I be waiting for some great release in 2008 (maybe with a front dial pad?)

Also, do any of you use a second (smaller) phone to just go out with if you don't need all the features of a PPC?

Thanks
