I have a 17" Macbook Pro 2.33 GHz, 2gb RAM, 160gb HD that is turning 2 this week I have been debating upgrading to the new MBP 15.4" 2.53 GHz, 4 GB RAM, 320 GB Hard Drive. I need to be able to sell my current MBP for a decent price and it is at about $1400 on ebay right now. Amazon is selling the new system for $250 off right now I am wondering if now is the best time to buy I currently have a glossy screen so the glossy screen on the new MBP isn't an issue for me, but the downgrade in resolution is as I am a graphic designer. Is the difference between the two resolutions super noticeable? My biggest issue in making this decision is making sure I get a good amount of money for my old computer and a killer upgrade in the process. I am afraid if I wait until mid-2009 my 17' will drop significantly in value. any helpful advice? THANKS!
