Hardware advice needed for 73 year old mum

The tipping point had been reached - my mum wants to get broadband.

She's nearly had a nervous breakdown trying to install BT broadband with a Sony viao 505. It's a long story, but (day 1)it wouldn't connect via an extension , (day 2)it has a non standard Ethernet connection and (day 3)the login details where wrong . Day 4 she decided she needed a new laptop or desktop.

I've said go wireless, so can anyone recommend a laptop for browsing and email, with a screen suitable for an OAP (no stupidly high pitch) which has built in wireless. It's taken her a few years to get used to windows XP, so no Macs allowed.

Also, any ideas on fax printer would be gratefully received. Are these wireless yet?
