Less is more. This is an essential addition to your laptop.

I decline to bore anyone with a lot of turgid technical detail.
These come in different sizes - I have the 750 GB model but they can go to 1TB (and maybe even more)

Password protected to ensure privacy to your documents.

I travel a lot, with a lot of documents. This is the 21st Century...and this can save you a few kilos in weight of carrying paper, save the environment and an awful lot of trees, and allow you to take ALL of your favourite movies and music around with you.

Essential for the business traveller - and especially one who needs a bit of relaxation at the end of the working day.

Stuck in Germany (or Wales, or wherever) with only German (or whatever foreign language TV)? Use this through your laptop. Watch what you want to, not what someone else dictates.

Kilos of paper documents to your next meeting? (and many of them not used)? Use this!
A walletful of CDs and DVDs for your laptop? Use this instead!

This is a small unit with huge memory , yet only weighing about the same as a sandwich.
Plug in and use.
No difficult techie hoops to jump through.
Reliable.
I can say no more.
