The HP Pavilion dm1-4027ea comes at an interesting time for portable PC laptops. Traditional laptops have had a turbulent ride of late, with a number of threats appearing to erode their market.

The first threat - netbooks - has been seen off pretty comprehensively. The diminutive machines offered a smaller, lighter and cheaper alternative, but at the cost of power and features.

In the end netbooks failed to capture the public's imagination, despite the efforts of some great products, such as the Toshiba NB520-10U.

Tablets, however - especially the Apple iPad 2 and the Samsung Galaxy Tab 10.1 - haven't had this problem, and have surpassed netbooks to become the laptop's biggest threat. Sales have rocketed so that tablets have succeeded where netbooks failed. Offering slick interfaces, a huge selection of apps and usually attractive and portable designs, tablets are a force to be reckoned with.

Their Achilles' heel at the moment is price. Top range tablets go for around £300-£400. You can get cheaper models, such as the Binatone HomeSurf 705 and ViewSonic ViewPad 7e, but they're not very good.
