Excuse me for being cynical but I will take this review with a pinch of salt as other reports show that, at least benchmark wise, there is absolutely no difference between Vista and Windows 7.
There was one set of benchmarks that showed no improvement: http://www.infoworld.com/article/08/11/10/46TC-windows-7_1.html/. There was another set of benchmarks done on a later build that showed improvements: http://blogs.zdnet.com/hardware/?p=3182&page=1/.
As for Windows 7 feeling "so much more responsive".. well, depends who is paying you to write that review innit?
Cynicism, conspiracy and an ad hominem attacks all in one. You're going all the way to +5 insightful!
