Hello, I was going to buy an iMac 27" 3.1GHz, for general computer usage, watching movies via netflix (on an absolutely beautiful screen *drools*), and casual gaming, but then I saw the recommendation not to buy it on this site as it was nearing the end of it's cycle. I used the chat online feature to talk to an apple employee who told me that the latest update was released in August, so it was very current. My questions are: 1) How often do updates come out? 2) Do they usually improve enough to make a noticeable difference? 3) Is there any way to upgrade an iMac without buying a new one completely? 4) What's coming in the next update? 5) How old is the actual iMac? 6) Unrelated, but whatever: Should I go Magic mouse or trackpad? (I plan to buy a Razer Deathadder for gaming, but for general web browsing, what do you think? Thanks!
