Hi guys, I'm considering getting my girlfriend a MBA 11" (with 4GB RAM) because her computing needs are light (web surfing, youtube, emails, IM, etc.) and she would like a small and light portable which are easy to maintain. However, a major use of her laptop is to make 720p HD video call using the Logitech HD Webcam C510. The specs page for the product says that So the 1.4 GHz cpu of the base MBA 11" falls rather short of expectations. The question is whether it is significant or not ? If you have the base MBA 11", can you still make HD video calls with skype or ichat ? I'm not sure whether skype video calling on mac is hardware accelerated or not, so can't count on the GeForce 320M. Please give me some advise whether the MBA 11" is suitable for her, or whether we should go for the MBP instead. Thanks !!
