From iOS 1.1.1 to today, every iOS device I had (with the grand exception of a jailbroken iPad with iOS 3.2.2 and a swap file hack) had this issue.
I learned one thing. It always comes down to the fact that Apple cheaps out on RAM. Oh, people told me so many excuses, from "Apple will fix it" to "You're just browsing wrong", but time passed, and the tabs still reloaded, text posts were lost, hedgehogs were angered.
