I'm coming from a 6 yr old dell inspiron 1501 with an archaic 1.something ghz processor and on ubuntu that was usable but a bit sluggish. I moved on to the hp dm1z which blew me away on performance with its amd fusion cpu. It also came 3gigs of ram. My sister just took the dm1z today since she also loved it and now im left with nothing but the old dell. I just talked to a guy from craigslist today and he's offering me a base mba 11" for $700. Will it be sufficient enough for me? I think it will but I just wanted to go by you guys first before I buy the thing. My uses are A lot of web browsing. I watch a lot of videos. Hours and hours of youtube and flash videos too. Does he air have trouble with flash? 4+ tabs open at all times. Multiple flash videos possibly I also download a lot of torrents so a lot of music and movies I will also download a torrent for office because I use word and excel a lot. I don't game but wanted to try batman arkham asylum too One more thing, since apple has a one year warranty with their laptops does that mean if I have a propblem I can bring it into a apple store even though I didn't buy it from them?
