I got to see and handle the ASUS VivoBook X202E awhile ago and came away pretty impressed.
For Php 25.5k cash, you get an 11.6 in. laptop with brushed aluminum finish, Intel i3 processor, Windows 8, touchscreen capability, and 5 hours battery life (reasonable considering the size).
Consider that the entry level Apple Macbook Air at Php 47.9k and there's some serious consideration going for ASUS.
