You pay ya money ya makes ya choice.
@Hunter, very well put, how many times do people walk into pc world to be told that this is the machine they need, the latest technology, internet ready, anti virus(demo) aaaaaaaaaaand a free printer with no ink.
Walk out of the shop...bargain, get home plug it in wow that guy in the shop really knew what he was talking about, course he did cause he knows nothing about the workings of a pc he's a salesman and you've just been mugged!!!
3-6 months down the line and the love affair is over, anti virus expired, Office trial expired, things popping up all over the place, its slow, it keeps freezing ya ya ya then who gets the phonecalls???? Thats right, people like us, who if they had come to see before spendin £800 in PC World would have ended up with a better machine, informative helpfull setup and continued support for half the price, but they couldn't be bothered, just wanted it quickly, well look at ya now..
Thats all really.
