I don't understand why people complain about this issue... Are you buying the iPad because of what it is currently, or because of what it could be in a couple of years after iOS updates? I buy the iPad because of what it currently is, and any additional updates on top of that are considered gifts from Apple. The only thing they are more or less required to do is update the current iOS for bug fixes. Everyone is wanting all these upgrades for free, but that's not how life works. This kind of business has been going on for many years and it really shouldn't catch people off guard.
Yes, people buy iPad with plans to use it for more than a day.
My concern with not getting iOS 6 is not that it doesn't get new features, I'm just concerned it might be rendered unusable because of the dependency on iCloud. Right now all iCloud devices work well together when they're all up to date. But imagine you have your Mac with the latest OS X and iCloud, but your iPad is running an old outdated iOS 5 with old iCloud support. Maybe it will mess up your iCloud data? I hope not, but this worries me.
It might be because I've never owned an iOS device that no longer supported the latest iOS version, so the experience is unfamiliar and scary to me. Especially in today's highly connected and interdependent world of iCloud.

If you buy an ipad less 14 days (maybe 30?) before announcing new one you can exchange. If you buy it after announcing new one, well, you're an idiot.
Why would you buy a new iPad in march when you should know, "Hmmmm Apple generally releases things a year-ish apart? Should I wait? Should I have enough sense to google "iPad 2" for rumors??"
Have you ever walked into an Apple Store, take a look at the average person there. The average and majority of people, especially ones buying iPads, are not the tech-savvy advanced computer users or Apple enthusiasts that you may find on this forum.
IIRC, they were saying something like every 2nd iPad was being sold as the person's first Apple device.
Those people buy iPads throughout the year, and not just during the first day when it comes out. So yes, there were people buying the original iPad days, weeks and months before iPad 2 was available, and not everyone of them could exchange for iPad 2.

Also, Apple isn't the only one who does this. Motorola introduced the Droid 3 only 11 months after the Droid 2 and dropped all but minor carrier support.
Samsung announced the Samsung Galaxy S II 4G & Galaxy S II HD were announced in August. The Samsung Galaxy S III was announced in May. The Some features will be lacking from the GSII HD.
Motorola announced the Atrix 4G in February 2011 (Even later for other regions; the latest was May for the UK). The Atrix 2 followed in just 8 months (5 for UK). The Atrix 4G has been dropped.
I know things are even worse when it comes to long-term support for Android, but why would you want to compare to someone who's doing even worse? Right now Apple is the best, they offer the longest support for their iOS devices. Do you want them to offer less support than Android?
Anyway, it is what it is so there's not much point in talking more about it. I'm sure Apple made the hard decision to cut off iPad 1 based on technical reasons, so it's just sad and I hope in the future their devices last longer. I feel bad for the iPad 1 owners, that's all (I don't own an iPad 1 myself, but my mom does).
