I use an iPad in the same way, after switching from an MBA. the big advantages of the iPad are inbuilt 3G (I get 5gb/month for peanuts on a special offer from a couple of years ago), battery life (I never got more than 3 hours from the MBA), I move more (lean over to do some browsing and shift my position or walk around). And most importantly I am far less likely to switch to HN or some other distraction. The big disadvantage is the lack of a web inspector, but I'm mainly working on back-end stuff at the moment.
