| Nope. Just iOS apps. Nothing terribly demanding.
Safari's a large part of the bloat though. The new Safari's total garbage with the app bogging down and deciding it needs to reload every page, often at times when I am not connected to the network and then I lose the content of the pages I had up.
YouTube movies seem to load into memory and never get released. Even when all the pages are closed. Some data structures are definitely getting stuck in memory. I've been forced to load as many Flash movies in an External QuickTime 7 Player and that's been helpful.

Weird. I’ve been doing fine with 4GB of RAM on my MacBook Pro. Just took a look and Xcode 4.3.1 is using ‘only' 311MB of private memory, the iOS simulator is using 3.5MB, and I’ve been doing a fair number of large builds today. I don’t use Safari, but Chrome is using 123MB for the browser itself and between 10-25MB per renderer (tab) process.
Are you building large C++ projects by any chance? It’s been my experience that large C++ builds have always created tremendous memory usage, both by the compiler processes, the linker and Xcode itself. For instance building Chrome takes at least 16GB of RAM if you don’t want to be bogged down in VM thrash.
