Quick feedback on air for photo editing

Hey guys, sorry for another 11 or 13 question, but I'm still very torn after reading this forum a ton and was hoping to hear from some folks. I'm looking at a new air mainly for photography organization and editing (main catalog on NAS, some local for editing while traveling). Most editing would be in photoshop elements with eventual move to aperature or lightroom. I'm not too concerned about power, but more screen size and quality. Also some minor video editing from iPhone/Canon 7D/Canon HF11 (still bummed it doesn't natively support avchd). Going to the store after work today, any quick thoughts would be appreciated.
