I'll tell you why:If you're willing to wait until April for the 2, why not wait until September for the iPad 3 as its rumored to be released then, heck at that point, why not see what 2012 will bring and maybe the iPad 4 will be a show stopper and it will be stupid to buy an iPad 3 in September because the rumored specs of the 4 are so much better.
- Waiting a few short months for an updated model is common sense and a smart move if you are able to.
- Waiting over a year for something just because that version, or the version after that will be better, is pathetic.
If I were in the market for an iPad right now, and Apple turned around and said that a new one will land in April, I'd hold onto my cash and purchase the better product. Nobody NEEDS an iPad at all, so I fail to see why you think somebody should buy one right now, despite an update being imminent. If they choose to wait, that's a smart move. If they buy now, fine, they can either keep it and suffer buyers remorse when iPad 2 lands, or they can sell it for a loss and consider it rented for a few months.
