Free laptops with broadband are not exactly new with Carphone Warehouse is already running a promotion with AOL Broadband. They have now replicated this offer with a £35/month 3 Mobile Broadband bundle. More information can be found at MobileChoiceUK.
Carphone Warehouse has a number of mobile broadband packages already, but the free laptop offer does not appear to feature yet. The 3 offer will get you a Dell Inspiron 1520 laptop, USB modem dongle, 3GB data allowance and 200 text messages per month.
It is not clear how long the contract is, but it is likely to be 24 months, in which case people might be interested in looking at the T-Mobile offer where for £20 a month the Dell laptop can had for £199.95 and a 24 month contract.
The 3G networks while bypassing the problems of telephone line length and ADSL coverage still often seems to suffer from patchy coverage so be sure to check that your chosen provider has a good 3G signal in your area. Obviously there is the advantage of not requiring a fixed phone line.
