Haha, I'm getting the same feeling. I installed the beta on my MSI U100, and performance-wise, it's actually quite decent. Still surf the internet just fine and everything, all the eye-candy is easily working (CPU-based, of course), and I think the only driver that didn't work at first was my wireless...which required me to hit Windows Update real fast...everything else "Just Works".
Yes, that's the exact same thing I try to tell people...my car's an automatic, but has a tach on it. At 35mph, my car is doing around 2k rpm...at 40mph, I'm doing around 1.2k...I don't do more than 5 over in neighborhoods...but on the open road an stuff, if I notice I can go up a gear by going FASTER, I do so...why waste the gas by going slower?
