Hi All. Just got my new 20" AL iMac - my first mac and am looking forward to a hassle-free experience (though it froze already on first boot!). Anyway, I'm sure that was a one-off, so, being totally new to mac, I'd love to know what you suggest I should do / install / set up on this new system. For example, would you recommend Firefox over Safari? Really grateful for your suggestions. Thanks in advance!
