Feel sorry for people running Lion on 2gb of ram, even with 4gb it's not the best. Lion with a decent setup is great, otherwise it's a big slob
Tell me about it! Lion significantly increased the beach ball occurrence on my mid-2009 MBP with 2G of RAM. Just iTunes, Mail and 7-8 tabs on Safari renders the machine slow as snail. And virtual machine is out of the question. I've just upgraded my RAM to 8G. Now I can leave my mac open for days with VM, Safari, Mail, iTunes, uTorrent, MS office running without any beach balls. Lion is definitely a memory hog.
