I have a 1 year old 32GB wifi + cellular iPad 3. Bought it in March of 2012 at launch. It's still going strong and I haven't felt the need to upgrade. I would like a higher capacity though, so I will wait and see what the iPad 5 brings.
iPad 3 here and it's about 6 months old won't be getting rid of it or upgrading it till it breaks because all I use it for anyway is basic browsing, gaming, watching videos and taking notes and I'm sure it will be fit for that purpose for a good few years yet
Got my 3gen April last year and planning to keep it for a while. Had a 2gen prior to that for about six months, but updated when the retina came as I spend a lot of time reading pdfs.
iPad 2 and its still performing as well as it did the first day I got it. I don't see myself getting a new one until at least the iPad 6 or maybe 7. The fact that I can charge it in a couple hours trumps everything else.
Bought my iPad 64 AT&T (1st Gen) on 5/15/2010 and just purchased my iPad 64 AT&T (3rd Gen) on 3/10/2013. I'll be passing the 1st Gen down to my ten-year-old slightly spoiled daughter.
I know a guy who rocks a first-generation iPad. It seems to be working fine to me. I imagine the battery capacity decreased slightly, because after a few hundred charge cycles, the battery capacity drops by 20%, according to Apple.
I suppose I should ask. how's the condition? Like new? Has it ever been dropped? Or has it, through no fault of anyone who touched it since you got it, degraded (e.g, did the performance worsen?)
