go for the branded ones, I used a vaio and i can say its better talaga kung may makuha kang support. Another brand to consider is Apple, a friend is showing me the features and mukhang ok, its not very expensive naman as the spec/price is comparable to other brand. Feeling ko ngayon eh parang medyo mahal tong vaio ko.
There's an Apple store sa greenbelt i suggest try visiting it to play with the products, may training center pa sila. Those who attend please leave a comment about sa training nila. if ok ba doon.
