I have just finished upgrading all my Macs & PC's to SSD's. While I've compared the boot times for each of them, overall they're all so fast a few seconds one way or another hardly matters.
Of greater importance to me is the day to day working experience.
Microsoft has done an excellent job with Windows 7 SP1. I'm also encouraged and impressed with the beta of Windows 8 I have on another machine.
Yet that said, my absolute favorite by a wide margin is my fully optimized and swift OS X 10.6.5. It's so fast, smooth & stable I simply cannot find a single reason to migrate to Lion at this point.
I have purchased and used a 13" 2011 MBA with it's Lion OS to see what the experience is like. While I can honestly say it's not for me, I'm certainly not going to bash it. The differences are sure to appeal to some, just not to me.
Who knows, its still early in the development curve for 10.7.x. Perhaps as time goes on and feedback continues to flow into Apple, future revs will be more to my liking.
Presently I'm far more concerned over the future of my highly prized Mac Pro. I don't even want to think what will happen if Apple kills it. The future of that segment as far as Apple is concerned is certainly a hot topic of speculation. Only time will tell.
