Nice one kestrelx
It does look good, but I think that were will be more to it than that.
Seems to be a lot of money to give away for a few adverts.
Here are the terms and conditions I copyed.
The following 5 key terms and conditions are for your guidance only, and do not constitute a legally binding agreement. Before delivery, you will be required to complete a written agreement, either by post or online.
1) On screen advertising: In exchange for your free PC, you must accept up to 3 minutes of on-screen advertising per hour of PC use. Every month, you will receive a cd containing adverts to be shown over the following four weeks. Each disc must be loaded onto your PC for the system to update. Should you fail to do this, your PC will be disabled.
2) The PC is lent to you for a term of 36 months, after which you will be offered a new computer and a new agreement, or you can simply return the old machine to a local collection point.
3) Your household must use the PC for at least 30hrs per calender month, or approximately 1 hour a day.
4) The PC must be connected to the internet at least once a month, and you must maintain an ISP (Broadband, 56k or ISDN) account throughout the term of the agreement.
5) The principle applicant should be 18 or over, and provide a home telephone number. We will conduct a security check linking you to the address given. Under certain circumstances, you may be requested to provide alternative proof of ID. This offer is restricted to one PC per household, and is only available to UK residents at this time.
If you accept these terms and conditions and consider yourself eligible, then please click on the 'Order your free PC' button to the left of your screen, and complete the short application form.
