Depends on so many things.

You can have wireless where you connect through a little portable modem or through your mobile phone. Or, you can get a wireless router (which I have) so you still connect through the phone line but you can use your laptop anywhere in the house.

Advice I was given:

Acer are shyt at replacing - they will keep trying to fix it if you get a lemon

Sony Vaios are the sexiest but very expensive to fix and not good value for money.

I was told to go for a Toshiba or an HP.
