Why Im still on Vista?

Old old engineering axiom...

"If it aint broke, dont fix it."

Until I need to upgrade to a new computer, then ill get Win7 along with it.
Probably IL2-BOB will make me go there, but for now everything I have works fine on what I have...
Including DCS-BS and A10C, FlamingCliffs, MSFSX, Open Falcon, COD-BlackOps, ROF-ICE, IL2-1946, SteelBeastsPro, etc.
And lets not forget Longbow2 runs great on Vista with little effort.
Same thing on my older dual2core with WinXP. No problems there either.
I also have some older laptops and a 2.4Ghz single core. On this system even the rockets in LB2 seem to work better.
