Yeah well that's why it's just my opinion/taste.
It's a flaw
in my opinion with what I use/enjoy when using a computer. Of course RAM is meant to be used - and that's where the problem is. I multitask HEAPS, and that RAM should be going towards what I'm actually focused on, not on keeping my system up and running. I often run a number of virtual machines too, and their RAM is limited because Vista is using half of my total, so it's not really easy to test and try things in the virtual machines...
Compatibility was an issue when I first got Vista (I didn't know about needing to integrate the sata drivers into my XP installation disk, so I couldn't set up the dual boot), of course XP's up and running alongside Vista now (among other things) so that's fine I guess...still a bit tedious having to constantly restart your computer just because you want to use a different program to do one simple task.
And of course your boot time is much more faster than mine. You probably have a lot more expensive computer, so it's probably better than mine (this was a pretty cheap computer, or so I think).
