No, it's worse for them. This is even noticeable when using Safari: the iPad can hardly keep a pair of pages in memory, it refreshes them all the time (very similar to the experience on a 3G). The iPhone 4's experience is much smoother as it has enough RAM to keep web pages cached as you switch between them.

Especially to those people. I bought one, and the lack of memory is very annoying, particularly when browsing (constant reloads).

It's pretty annoying, Atomic Web is always running out of memory
