thanks for the answers sirs!
Fortunately, my friend had an HP mini note that runs on intel atom and she let me test ableton live 8 on it. Unfortunately, it was an "all-around" laptop with just 1gb ram and so lumabas talaga yung limit nung cpu. Actually gumana naman, nagkakaproblema lang sa pagsunod nung tempo pag nagrerecord na ng midi. It's not really latency kasi pag nagpplay ako w/o recording, tama naman yung tunog. Pero pag nagrecord na, yun na hindi na sumasabay sa pindot ko yung sound na narerecord. And it was only ONE track.
Ako kasi I won't really buy a laptop for music purposes lang eh, mine would also be "all-around" din so I guess MY OWN conclusion for this thread is that I WON'T buy an Intel Atom laptop kasi masyado talaga siyang mahina kung hindi nakaconfigure (siguro) for music lang. Guess I'm gonna start looking and saving up for a better one
Thanks for all the help sirs!
