I'm glad I did. It's now a constant companion. I actually prefer surfing the web with it over my laptop because it is small, weighs less, and is quite speedy. I haven't seen any of the wireless issues some are reporting. Mail is good, but I can't wait for that unified inbox coming this fall.
I had some need to control a PC, so I looked around for some kind of remote client for the iPad. There were plenty of them the iPhone, but I wanted full resolution. I wound up with RDM+, which is a US$9.99 app that lets me connect to my Macs or PC without any firewall fooling around. Screen updates were fast enough, and installation had no hiccups. I'm sure there are some other solutions, but RDM+ worked very well. I took my iPad to a restaurant and I connected to my PC with a click.
Battery life has been amazing. I use the iPad pretty heavily, and can easily get through 2 days or more without a re-charge. The screen is excellent for displaying still images and video.
