I bought a WiFi and a WiFi+3G. I'm finding that I really enjoy not having to tether my iPhone to the iPad when I want to get online. I have used about 3gigs of cellular data in the past 14 days on the iPad. So I may be atypical. The double data bill is the only issue I have. If only AT&T would come out with a reduced rate iPhone + iPad plan everything would be perfect. Still at $60 for both devices, is in line with what they would charge for a DataConnect USB stick with a 5GB limit.
