hi, please help to provide some suggestions. this will be my first MacBook purchase. currently I have 15 rmbp with 2.3ghz, 16gb ram, 256ssd coming this week. after reading and looking at the apple store, I am thinking the rmbp is a little too advance for the graphic card and everything else... so I am thinking of getting the 1.8ghz, 8gb, 128gb 13.3 air.. it's light and very nice.. perfect compliment to ipad3.. my question is I intend to use the MacBook for 75% basic stuff (surfing, office tasks, ppt, online video) + parallel for some very light gaming like navyfield.. the other 25% for adobe photoshop for my baby photo album and hd video editing with final cut or iMovie .. all files stored on external drive.. will the air be good enough for the video editing or will it take long time to load etc? I think the rmbp should be ok but its too expensive and prefers to wait the next version. Tia!
