hey monkey- for my purposes (basic stuff such as e-mail, internet, etc) SL is just dandy. I'm pretty sure the following are working, others can fill in if they want to. Wireless, bluetooth (although i can't turn it off except in bios but i don't use it), sleep, wake, all power functions, sound, screen brightness, battery life is very good (around six hours), all the standard plugins (java, flash,etc.), i've heard the software update works but it's not a compelling enough update to try it for me, and i'm sure there are things i'm leaving out but all in all this install is going to last me a long time, until there's another major update prolly. It's definately worth a try in my opinion.
