Dell has a current Facebook promo for their Inspiron 3420, from P25,990 in retail to just P18,910 till May 10, 2013. If you're using Facebook Mobile, you might see it as a suggested post. I availed of the laptop today, its not bad for the price (Intel Core i3, 4GB RAM, 500GB HDD).
The laptop is probably entry-level to mid-range depending on your need. The unit has Ubuntu 12.04 LTS installed by default (that means its certified), but Dell also gives a Windows 8 installer and a bag.
For the price and specs, I'm quite happy with this purchase. I think you can only get them from the Dell Concept Stores. AFAIK, they're only at Megamall (where I got mine), SM North EDSA and Cebu.
