As per my experience using Windows laptops:

MSI - my first ever laptop which was bought last July2009. Got it for 27K with free mouse. After 2 years the hinge broke. Took it to megamall for repair, cost me P2500 IINM. Still functions even now as I've given it to my brother in the PH. Battery life is crappy, can only do 1hr nowadays.

Dell - wifey's first laptop bought here (ordered online thru Dell site). Around $600 that time and it was actually good. Still functions up to this day but much slower, and weaker battery life.

As per experiece repairing laptos:

I think I have repaired about a hundred laptops during my work as a Computer Technician. It ranges from infection from viruses, trojans, reinstalling OSes, installing software and security programs, calibrating and replacing battery life, upgrading RAM, HDD, replacing non-working fans and heatsinks, broken screens, coke-spilled keyboards - the whole nine yards.

Most of the laptops i've repaired were Acers, HPs and e-Machines. For every 10 laptops that went in our shop, 7 of then are Acer.
Not actually bashing Acer for having poor quality, maybe it's their low cost that drives people in buying them.

To sum it up, for 30-35K, find a used 13" macbook or an older 15" macbook pro. They are really durable and withstand the test of time (and user's abuse).
They can be easily upgraded by swapping optical HDDs to SSDs and/or adding more RAM.
