Hi everyone, I recomended a macbook air to my sister back in July and it was the highest spec of MBA (2.13Ghz, 2GB Ram and 128GB SSD). I am still using a DELL D420 and still wondering if I should get the same MBA, while Dell just update the Adamo spec, which to me is pretty nice. (Intel® Core™ 2 Duo SL9600 (2.1GHz/800MHz FSB/3M L2 Cache), 4GB DDR3 800MHz Ram, 256GB SSD and Intel® GS45 Graphic with 256MB) I can only judge from the spec that the onboad front side bus on MBA is better 1066Mhz vs 800Mhz and the L2 Cache 6MB vs. 3MB (I think this is important). Apart from these two points, the new Adamo has 4GB Ram vs. the 2GB (No upgradable) and 256GB SSD vs. 128GB SSD (This is importnat for me since I have a lot of files and programs) And I am still used to Windows system...but I am willing to change if I am convinced that MBA is better. What about you guys? anyone shares some thoughts and experiences here for me? Thank you!
