Well, as has been commented on elsewhere on the internet. The sale of the Nexus 4 didn't go that well. i started trying to buy one at 8:10 and the checkout process either crashsed with an ambiguous error and you had to start again, or Google wallet failed miserably. Stock would fluctuate between being in stock and coming soon. Gave up at 8:45 as had better things to do.
Didn't manage to bag one - but will try again in a few weeks time.
