Obviously for us home networkers with big plans, if 1100 machines are necessary for the number three spot, your going to need at least 1500 for the number two spot, so start saving up your pocket money.
Missing is the former number three called "Big Mac", a cluster of 1100 off-the-shelf Apple computers coupled together by software. It made an impressive debut six months ago, but was removed from the list because it has been dismantled for hardware replacements.
