I'm running OS X 10.6.8 on my MBP 2011 and am totally happy with it. I'm a simple user: some surfing with Chrome, watching videos with VLC, some Office 2011 that's about it. I've heard Lion brings upgrades to mail and touchpad. I don't use Apple mail, I use Gmail online instead. For the touchpad I only use the simple features. I don't use stuff like expose etc. Do you think I should upgrade? Or should I just stay with what works for me. If you think I should upgrade, why?
