Yep, if you notice I mentioned I'm running 32-Bit Lucid on my laptop with 4GB Ram... r...@aspire:~$ uname -r 2.6.32-19-generic-pae r...@aspire:~$ free -m total used free shared buffers cached Mem: 4012 2820 1191 0 138 1418 -/+ buffers/cache: 1264 2748 Swap: 502 0 502 This is on Ubuntu 10.04 Beta 2 Desktop. I'm considering upgrading to 64-Bit when it comes out on Thursday though as I've started a new role which involves some Windows Server stuff and I dare say being able to run the 64-Bit Windows server 2008 on VirtualBox would be handy for me.
