it's all good - mostly
The problem with things like Mi-Fi is the battery doesn't last anywhere near as long as the iPad. I think the Verizon Mi-Fi is quoted at 4hrs for a single user connected.
my MiFi has a car adaptor, and yes whilst it's not as goos as true wifi, in the UK the speed is as good as built in 3G.
Whilst you are right about battery life, for me it's a standby, if I can't get access to wifi and at only £15 a month its good value.
