Re: My next machine will be a desktop.
If you want a good **powerful** desktop, DO NOT go thinkpad, lenovo, or ANY 'ready made' PC..... those are made to a price, NOT a spec..
It is VERY simple to 'make your own' PC.. some web companies will even build it FOR you, to parts you have selected from their website!!
overclockers.co.uk got me a 3Ghz I5 with all the extras for half the price of most shop bought ones!! :)
