Mobile broadband deals which offer customers a 'free' laptop as part of their package can often look better than they turn out to be.
This has been suggested by specialist computer magazine PC Advisor, which has labelled the economically-sized netbooks included with many offers as "uncomfortable".
The publication has also drawn attention to the fact that many of the offerings are only available on long-term contracts totalling at least 18 months in many cases.
According to PC Advisor: "Add up the price of a mobile broadband contract over 18 months or two years, and you could be paying over the odds for a system that turns out to be uncomfortable to use for prolonged periods."
T-Mobile recently launched a new mobile broadband bundle featuring the Asus Eee PC 904HD netbook on a £25 per month subscription, for a period of 24 months.
