I am a proud owner of this baby for more than year now. I tell you what I did not experience anything apart form solely posititve things with this laptop. It has never lat me down, there was no single breakdown or even slight hardware or sony software problem.
Strong performance of 2.7ghz processor is backed up by reasonable amount of RAM memory (512mb). From my personal experience it was enough for all the applications I was running on this computer. High resolution screen is also a perk, very nice to watch DVDs and videos on it.
Another thing I really liked about this laptop is the feel you get from the keyboard - nicely firm but at the same time very responsive.
On the downside, speakers are kind of pathetic. They can provide a decent quality but there is no chance to get any volume from them. But that's the only drawbag a can think of.
