does anyone think this is needed? Atm I have 4GB. I've installed Lion and noticed that it is a tad slow sometimes when loading apps (bounces for a while), but I've read that a clean install of Lion would usually fix that. Should I wait a few years, when it starts getting really slow and install it then? (along with a SSD - hopefully they'll be cheaper!) I don't use very intensive apps, I just use a lot at once. Steam, word, spotify, itunes, chrome, mail, skype. What do you think?
