Well this is going to stir it up for sure - I'll be brief !
I could not resist firing up Firefox under Ubuntu - this is the last version in the 3.x.x series - purely out of interest of course ;-)
FF booted from scratch in 5s - and it loads pages just as quick - and when your using it, it has that magic "Feel" - a certain zip she's very quick under Linux.
One slip up under W7 and I'm back to Linux !
Do have Fun - 10m is open ;-)
