For this month's comment competition Heathrow and Pocket-lint have teamed up to offer you the chance of winning a Sony Reader PRS-505 just in time for the festive season.

With the ability to store hundreds of digital books, the Sony Reader allows you to carry an entire library wherever you go, all accessible at the touch of the button. Using innovative E-Ink technology, the Reader features a high-contrast paper-like screen with no back lighting – meaning it's gentle on the eyes and provides hours of reading, even in bright sunlight.

The Sony Reader is one of hundreds of great products available to view on the Heathrow Gift List website – a free service set up at to give passengers top tips on what to buy at the airport. Free to set up, indecisive Christmas shoppers can create up to six personal lists, choosing from 170 budget to blow out gifts from categories including For Him, For Her, For Kids, For Foodies, Gadget Lovers and Indulgence.  

This year, for the first time ever, Heathrow is also offering those who register a gift list on the chance to Reserve & Collect - a free and convenient service that allows passengers to reserve items from the gift list and then collect them at the store prior to boarding their flight.  Users simply need to look out for a "Reserve Me" tab on each of the product pictures featured on the microsite.

To be in with a chance of winning the Sony Reader all you have to do is comment on any story on Pocket-lint. It doesn't have to be in depth, detailed or technical, but it does have to be useful, helpful or funny.

You don't have to sign up to comment on the stories, we just ask for your name, location and email address - that does not show up online and is not passed on. At the end of the month the Pocket-lint team will choose what they believe is the best one.
