Hi, I currently have a Dell inspiron 14r Intel® Core i5-2430M (2.4GHz, 3MB Cache) processor 6GB installed memory 640GB hard drive 8X CD/DVD Burner (Dual Layer DVD+/-R Drive) 14.0" High Definition (720p) WLED Display with TrueLife Intel© Centrino© Wireless-N 1030 with Bluetooth 8-in-1 Media Card Reader Integrated 1.0MP HD (1280 x 720) webcam 6-Cell Lithium Ion Battery (48 WHr) Genuine Windows 7 ® Home Premium (64-bit) Dimensions 13.5"W x 1.29"H x 9.68"D (4.89lbs) 1 year warranty I want to go Mac. Are there any Air models or Pro models that will be a slight upgrade to these specs? Is the pro my only choice? I looked at the air but they only offer up to 4gb of ram, I'm already pushing hard with 6gb of ram, and want to either stay at 6 or go higher. Thank you all in advance!
