I wish the new Ipad 2 could be upgraded to LTE. I really want to buy one, but don't want to spend $800 on a device that will be outdated next year. I would pay to have it shipped to Apple and upgraded to LTE.
I agree with Garz, something new each and every year, and if you wait for every new feature, you'll be waiting a long time... and you have the choice to spend less than $800 and have a great product, buy the $499 16gb device, try it if you love it sell it next year and buy the latest greatest iPad, heck that's what I'll do.
Personally I didn't see enough features on the iPad 2 that I wanted so I'm skipping a generation and waiting until next year, love my 1st generation iPad!
