They have to separate the MBs and MBPs as much as possible now that MBs are getting the "MBP like" features of the past (aluminum casing, improved graphics card, LED display, backlit keyboard, SSD option, etc.) I think this is why we'll never see a 12" MBP again.
They will drop the plastic MB either in January or September. MacWorld '09 will introduce the 17" MBP with this new enclosure, new MacPros, and do something with the Mini. Don't forget Snow Leopard comes out in June.
However, I am looking at getting a deal on this year's model. The 15" with 2.6 processor with the fast (7200rpm) hard drive should be a real bargain right now.
What's the deal with the glass screen? I am on the road all the time and I beat my machine up a little. Also, I do a lot of summer outdoor shows in extreme heat. It seems this new model would be more fragile and it's operating specs are more temperature restricted.
if my budget were to be 1800. should i get a macbook laptop or a dif kind?
If the 17" is also a glossy, I'll be skipping the upgrade.
