Possibly... But it's rumoured that saving and reloading often is a cause of corruption. I haven't noticed any difference personally, neither increased stability nor corruption.
The memory leak introduced by patch 1.3 was only significant in people who didn't have a lot of RAM. I have 1 GB and never noticed it in either vanilla or EB.

A suggestion might be to install it into c:\Games, for those who can't think of where to put it.
Pardon me for being dense, but why is this a problem? I have all my games installed there. I use XP, by the way.

While I do not have any problems with this myself, there are reports that it crashes occasionally when alt-tabbing, yes. If you play in a window (-ne switch) you'll not have any problem with alt-tabbing, but it may run a bit slower.
I haven't noticed any instability as result of alt-tabs, although it was said to cause instability in multiplayer with R:TW 1.2 (I haven't played MP since then). I do recommend using FRAPS for taking screenshots.
