Good deal? The UK public service seems to think so. http://www.digitaltrends.com/computing/xp-please-uk-gov-pays-9m-extend-support-plan/#!CZSk1 Figures in that article point to ~650K computers still running XP in the UK public service. So ~$15/machine to receive updates is pretty cheap in the grand scheme of things, especially when compared to a fleet wide upgrade even if the replacement OS is $0. It will be interesting to see if 3rd parties jump on the bandwagon and start releasing these updates for general consumption. It will be even more interesting if this becomes an acceptable method of updates, and lets people keep XP around even longer.
