Think of the problems if it goes wrong.
Aldi, Lidl sell pretty good computers with good service.
Problem is operating system but some laptops in Portugal are being sold with Vista in Spanish, Portuguese,English . Language to be chosen at first set up.
I have run XP in Portuguese for over a year now with no language problems despite having little knowledge of Portuguese. HP have a good range of machines as well and are well built and reliable.
Guarantee may be better in Spain than Mesh uK
