After nearly 3 years of solid University abuse my laptop is frail and close to death.
During May I need to buy myself a new laptop to replace my beloved Fujitsi-Siemens LI thingy

and need some advice as to whats best for my budget.
- I need to have at least 3GB+ of RAM.
- A massive HDD isnt that important to me really as I use external HDD's to store my important stuff.
- Needs to come from a reputable shop that I can either collect from (PC World, Comet etc) or one that will deliver to me.
- Needs to have working versions of Microsoft Office (no trials)
- Needs to come with Windows 7
- Need at least 4 USB ports
- Need a DVD-RW
- 15.6" screen or bigger
- Memory card reader would be nice
- Wireless
Cant think of anything else at the moment, and any advice is greatly recieved
