First generation Apple products have been known to be feature-poor, overpriced and having all sorts of problems.
Is this generally true of late, the problems that is? I can agree that missing a camera on the iPad looks to be a mistake and there's no doubt that it's expensive but problematic? The only real problem I can think of is the wifi one and if that can be fixed in software it sounds more like a problem with router/iPad interactions than a major iPad problem.
But do you want to spend your life with waiting? The iPad is a much-anticipated product, so why not just enjoy it and suffer a bit of depreciation in half a year? Is it worth $300 for you to have an iPad for a year?
I plan to keep mine for some time until something much better comes along. perhaps the third generation device with 20 hour batter, front-facing camera and all the other goodies. So perhaps two years...
