SWVGA is 1024x600 resolution.
As far as I can tell that 'Netbook is an Advent Milano 7
Sold @ PCworld.co.uk it's being sold now for £209
or about NZD 450
It won't have a DVD player to load CD/DVD movies. It's weak CPU & graphics chip might mean stuttering HD movie playback.
It will work Ok, if slowly, for working with word processing, e-mail or web browsing. It might have trouble doing both at once.
As long as it's not stolen property (check the owners purchase receipts, etc) it's probably a fair price for a 'unused' 'Netbook with six months left under warranty (which you'd have to ship to the UK to get honored).
