Geesh, how can you make an assessment of a new operating system that's only been out for a day? I went through WindowsME, Windows XP, Windows Vista and Windows 7 and survived. Now I think I can surely survive Lion.
BTW, I just bought my Macbook Pro 15" on 28 June 2011. I'm just getting used to the whole OS X thing but I can tell you that it's a lot better than what I've used in the past, i.e., Windows XXXX!
Give Lion a chance...I'm sure it'll just ROAR someday! 🙂
