Being one of these people that has to carry my laptop around a lot from location to location, i need something that will offer me protection from the elements and the durability because I like my laptop accessories to last. At £33 this Crumpler Silver Dig medium notebook carrying case is ideal, and if it didn't last I would be most annoyed having spent such a decent chunk of money.
The laptop carrying case has a main pocket fastened with a velcro pad. I would prefer a zip for piece of mind personally, but the way the front flap comes all the way over offers protection from temptation. There is also a mesh pocket within the laptop pocket to hold chargers and mice etc. I am pleased with the look of the laptop carrying case, but a little dissappointed that it doesn't have a zip on the laptop enclosure.
I do use this sometimes, but my laptop carrying bag (another review) offers me more protection from thieves and with this case I wouldn't trust it on public transport, for example a busy tube in London would be a no no for me. The fact the case comes in a number of colours as opposed to just black is a plus, although I think the brighter the colour, the more unwanted attention you will get. Overall this is inadequate for everyday use as I would rather keep my laptop on me than look cool. I would suggest you either go for a carrying case that is more discreet and has a zip, or a rucksack designed specially for carrying a laptop.
