Looking for a laptop

[Desmo]

I was always going to ditch my desktop once our house was done and grab a laptop instead but it's becoming something we'd like to get sooner rather than later. At the moment I'm using the TV as a computer display so in the evenings we can't have the TV on at the same time as I'm on the net. If we have the TV on and Sinead is on her laptop, I can't now get access to the net so it's becoming a bit of a pain.

So, I'm looking to spend around £500-700. I'm only really using it for net and maybe a few other bits 'n' pieces. Nothing too strenuous going on though. But I still want a pretty quick machine. Mind you, my current desktop is only a 1.4Ghz Athlon so anything I get should be quicker

Here is what I need:
£500-700
15" screen minimum
DVD writer
Wireless
Bluetooth
80GB HD - at least
1GB RAM - at least
Battery Life - Reasonable
Weight/Size - Not an issue

I specced up a machine on Dell last night and it was quite good spec but wondered if you guys know of anything else.
