Mine is in the rev. E range - had it for a week now.
- It has good fit between the top & base,
- there is no whine of any kind (other than the one I hear all the time now);
- compared to my MDD PM, it's silent enough, and at least as fast;
- (have been unable to really put it thrugh its paces yet);
- Airport connectivity issue was solved by the 4.6 update last night;
- the space between the F-keys & the screen gets hot - snatch-your-hand-away hot, so that prob is...
