Bill, if your happy with your laptop just buy an external hard drive, Amazon is selling a 2 terabyte drive for £69.
Sad movie collector that I am I have 6 external drives which add up to 8 terabytes.
Just keep away from Seagate drives, tendancy to go tits up.
For Roger, a terabyte = 1000 gigabytes.
Just as an example, in 2000 I bought the LAN system for the Brunei frigates we were building, they insisted on a half terabyte storage, totally unheard of then.
The entire BAE SYSTEMS network ran on 250GB.
