Unless you're running a 64bit version of the OS, then 4GB is your limit anyway. 2^32 = 4GB is the maximum addressable space with a 32bit OS. (1)
I'm sitting here running Vista on a laptop with 2GB of RAM, have a few apps open and am running the Aero interface, and it's only using 1.17GB at the moment. For anything other than video editing or CAD (ie 'normal use'), 2GB should be more than ample. Most of the extra RAM is just used as a disk cache rather than being used to hold apps.
(1) Advanced and Enterprise versions of Windows Server can use more than 4GB, but there are disadvantages to doing so depending on the apps your running.
Was just about to mention 32bit kernel memory management with PAE extensions and boom you beat me too it mate

A fair chunk of memory is wasted when you've got 4GB in anyway due to reservations needed for the bus etc..
Was impressed with Vista on your machine when I saw it at work that time, still not touched it since, spent this week battling with HP-UX, command lines are all starting to look the same!
@ Wylie, yeah I was happy with 2000 Pro, XP with the latest services packs and hotfixes on the right hardware with the right drivers can be good too though. I had an IBM T43 that was trash but now running a T60 and it's a different world, never have any problems really and I do give the system some abuse just never play games or anything silly like that!
Maybe we had a dodgy batch of the T43's but they'd just randomly lock up, it used to absolutely do my head in!
