its not a philips. its a cheap shit thing with a philips badge on. A customer of mine bought one of these off his own back, and phoned philips for support on it as the screen was flickering, he got referred to some place in hong kong who speak terrible english and were no help whatsoever. ended up junking the think 6 months later as Philips nor PC World wanted anything to do with it
Dont buy from PC World on principal - theyre a bunch of useless cunts who will sell you a bag of shite
Have a look on Misco, ebuyer, or the dell outlet store. If you cant stretch your budget to an HP, try an Acer or Toshiba.
http://www.laptopsdirect.co.uk/ are also worth a look
Try to avoid Celeron or AMD chips too - avoid Vista too, even basic will run like shit on a entry level laptop (i personally wont touch it at all)
