No I would not. I was really excited about every new release they have had since 10.1! But then I seen the the "features" they were adding to Lion and I wasn't impressed. Then when it launched, like a good little Mac fanboy I upgraded. They ruined spaces and expose. They took away my ability to manage my own files by saving them when and how I wanted to. They turned my second monitor into a paper weight for "full screen" apps.
And then there are the bugs... pretty big ones, that still exist after two updates. We have a brand new imac that came with 10.7.2 preinstalled. It locks up constantly. We finally discovered that it was Time Machine locking the whole machine up. We turned if off and its not locking up anymore... to bad the wifi is still flaky. This same iMac running Windows (and now even Snow Leopard) doesn't have any of these problems, so its not the router or the computer.
So no I don't recommend it, in fact I recommend NOT using Lion, even if that means you have to go to Windows 7 or Linux. I think Lion, which was suppose to finally be about the Mac ("back to the mac") has proven that apple doesn't care about their computers any more. They don't care about the people who supported them all the years before they had the iPhone, iPads, and iPods running iOS. Its really sad.
