To be honest, that is kinda expensive for the specs. I bought a laptop recently for the same reasons, and picked it up for £330 including P+P with the following main specs:

• Intel Core 2 Duo Processor 1.77 GHz
• 2GB RAM DDR2
• 160GB Hard Drive
• Windows Vista Home Premium

If you're looking to run more than one memory-sucking program at once, that is a good laptop to buy, but I suggest you do a little more searching for a cheaper one (try eBay).

Also, kinda unsure about the Turion x2 processor, I'd go with Intel, but that's personal choice.
