A lot of people in this thread are mistaking the iPad 2 as "lasting" ten years but in reality it was marked obsolete in every country except US 2 years ago and probably long before that in reality. But I guess if you didn't read that part then you're unlikely to have read this comment 3 pages later lol.
Apple products useful life last about 4-5 years - still way better than industry average, but def nowhere near 10.
That said, I just rewatched the keynote for this for some reason today and Steve convinced me to trade my current iPad in for an iPad 2. You just can't ignore the 33% thinner, 2x CPU, 9x graphics stats...I'm sold.
