Hi, Mi first post, a lot of time as a reader. I'm a switcher, i buyed recently for my home an iMac 24 ", perfect, and a mac mini as media center (perfect). I want to change my sony vaio tz 11" with the new mba. I use the vaio at bed, to watch video, and for an application that see the security cameras in my house, i use a bluetooth sony br-50 for no disturb my wife. Differences between vaio and mba -------- vaio ---- mba noise --- nothing --- after de 10 min 6200 rpm (noisy) battery --- 4 hours --- 1,40-2 hour watching video kernel panic --- NEVER --- 1-2 time every night (parallels issue) bluetooth a2dp --- 100% --- impossible, it's stop every 3-4 seconds heat ---normal,60celsius--- 70 celsius processor --- 1,2 ghz(1 core) ---1,6 core2duo I've made a mistake, the vaio works better for my use, the mba, has a lot of stupid things, the extreme sensitive light detector for the screen, the keyboard illumination that doesn't work (works in reverse). The thing that i can't understand is why with more processor (1,6 core 2 duo versus 1,2 core solo) needs around 30% of the 2 cpu to see the last chapter of lost... i'm lost. Now my last test will be install windows xp in bootcamp, to see if the problem of the heat, noise, bluetooth dissapear... Be careful to decide to buy the mba, it's pretty, yes, it's apple, yes.. but have too many limitations and problems.
