Nice review! The one issue I have is that it requires another sleeve. I'd like a PC Card version to plug into my existing two-slot sleeve so that I can also use a wireless modem at the same time. There is also supposed to be a sleeve coming out that turns the iPaq into a GSM phone. So I'd be carrying around three sleeves. Yuck. GPS is definitely on my wish list, though, if I can find the right form factor.
