I was a Mac user back in the IIc days. However, I've been a PC user ever since that time. Vista is such a piece of buggy junk that I did not feel comfortable keeping it on my main machine and I'm really tired of supporting MS. Everything from their game consoles to their OS is just so unreliable. I recently tried the Safari for Windows beta and was very impressed with its speed. (It renders some pages so much faster than Firefox or Opera.) Anyway, I'm now looking to get a Mac for my next main computer. Here's what I care about the most: Mathematica Adobe Photoshop Low to Mid-range gaming (Love strategy and puzzle games.) Here's what I do not care about at all: High-end gaming Laptops All of that having been said, I would like to have a computer that will last for a few years. I'm not someone who purchases a new computer every year. I usually go about 3 years between purchases. My questions: 1. What lines are overdue for updates? I'd really like to avoid purchasing, say, a high-end iMac and have Apple announce news ones the next day. I know that phenomenon is nothing new in the computer world, but I'd think it would be a bit easier to predict when you're only concerning yourself with one company. 2. How long does it usually take Apple before it drops the price on its systems? The Mac Pro 8-Core looks very appealing (obviously), but it's a bit too expensive for me at this point. 3. What the heck is up with those RAM prices? 4. What have your experiences with Airport Extreme been like?
