your quite lucky. using the system properties in Win98 my 1.5ghz Powerbook came to a 300mhz P3, or was it P2. anyways it was dog slow. didnt run an application i was crossing my fingers for too... the only PC-only app i really need to use.
was a lot slower with XP. after installing XP i had enough and jumped back to 98 which is alright.
On an 800Mhz G4 iBook with VPC 6 running 2000 I got about 330MHz which is pretty similar to the 294MHz that the system properties claims. Funnily enough, it's the same in XP Pro... Of course, 2000 is heaps smoother though.
