Hi there, been a lurker for a long time and finally decided to post. Ive been waiting for the updates that came out yesterday for quite a while to replace my aging Powerbook G4 1Ghz 12-inch. The Powerbook is lagging in some things that I use the computer for, such as photo editing, internet surfing, chatting, Word/Excel, moderate to heavy iLife use (all programs), light gaming, chatting, light HTML coding, etc. I have an external hard drive already, which minimizes the trouble for lack of memory space but I dont absolutely NEED to change it right now, although it would make a huge difference performance wise. I saw the new long-due updates for the MBP but had a question in regards to the frequency of updates from now on. If I was to buy the computer now rather than wait for the mid-year Montevina updates, what would I really be missing out? Blu-ray? New keyboard (are they that much better?), complete overhaul of the case (how much can it change?), chipset performance? Im thinking of going with the base 15 model with a 250GB HD. Any feedback is much appreciated. Thanks!!
