well at work we have 16 dell laptops and have been using them for a yearand the administrator / tech guy says that they are ok.
We use them in the community getting pcs to people that have never used them both young and old so they do get a bita fare bit of a bashing. nothing bad so far/
but i did see a laptop in safeway a few weeks ago cant remember the make but it was only 599 seemed a good price.
And also Lidl on occasions have stonking laptops for only 999 cant remeber the make but the specs are high with loads of extras,
hope this helps
