No, I originally had an ipad 1, and was consulting for my family when this thread hit.
My stepmom has an ipad 1.
I was having a problem while posting to this forum from my computer but that's immaterial.
I told my stepmom she might have to buy a then-current ipad 2 if performance problems occurred upon upgrading to iOS 5.1.1 which her software (Things) required.
On my own intuition, I updated all of the apps before performing the upgrade, because I wanted to do things in a more or less sensible order.
She has not seen any crashes and continues to use the ipad to this day.
I have occasionally been able to get specific URLs to crash, but it sometimes improves by enabling private browsing mode, and can sometimes stay fixed by toggling it back off.
For the record, I have had great luck dealing with Powermax. They allowed me to trade in my ipad 1, and when I lost my ipad 2, they sold me another used one, and I'm using iOS 6 currently, but will upgrade to iOS 7 as soon as I get my 3G model in exchange for the wifi only one.
