Because they're too big to slip into a typical bag and carry around, 17" laptops aren't for everyone.
However, if you're keen to have a big screen and a keyboard with a numeric pad, and you want a machine you can move round the office and take out occasionally, a 17" model might be for you.
If you want to see how a laptop with a larger screen suits you, Dell's Inspiron 17 is currently available from just £335 including VAT and delivery.
That's a great price for a PC which has received decent reviews, and while the entry-level model isn't exactly over-powered, it still has enough oomph to run standard business software like Microsoft Office.
The Inspiron's real stand-out feature is its screen, which is crisp, clear and manages a resolution of 1,600 x 900 pixels. Most laptops in this price bracket make do with lower-resolution 1,366 x 768 screens.
In all, this is an excellent tech bargain if you're looking for a big laptop at a small price.
