Megacrazy, have you tried increasing the memory cache setting to 40 mb and then doing the same test? It seems quite a bit better to me after I did that- I still see the checkered pattern occasionally, but it seems to go away in just a fraction of a second.

It makes sense that this would be the case, because the engadget homepage is big and must take up a lot of memory in rendered form. Increasing the cache size means that it has to do a lot less rerendering. There is also an "automatic" setting that I haven't tried yet.

Of course, some other smartphones that don't do true multitasking can afford to always use the maximum amount of memory available.
