Actually yes, yes, 1000 times yes.
Have you tried browsing in Safari on the iPad? Unlike the iPhone, where you can keep about 4+ tabs open at the same time without the device flushing the contents of previous pages, the iPad only gives you one -- maybe two if you've loaded a text-heavy page -- before previous tabs get flushed and you have to reload.
This leads to losing your place, re-reloading pages you've just loaded, and actual content destruction if you are leaving a comment (such as this) and go to another page to check something, etc.
It is, in fact, the only complaint I really have about the iPad.
If the new iPhone operates in this same manner, it's going to be a big step back for the current iPhone browsing experience. Maybe there will be an implementation that makes everything work, but considering the iPad issue and the fact that multi-tasking is coming with 4.0, 256MB is disappointing.
