I wonder if this has anything to do with the buy back of Dell by its original owner. (Mr. Dell??) An appeal to win back the geeks. On the other hand it might be just calculated free marketing.
I would never buy anything from Dell anyway but its a good gesture. But scan.co.uk have been accepting bitcoin for ages and that is obviously available to UK. I hope more companies start using it. I have a fair chunk of litecoins stashed away so hopefully all this activity will boost the value of that
