If you're not in the UK, then you've probably never heard of Dell Swarm, a group that residents can join to save money on gadgets. Deals are offered for a limited time and in limited quantities, so it's sort of (yet not really) like Woot here in the US.
Anyway, the Dell Streak was just "swarmed" for £199 and ended up selling out in 11.5 hours. The good news is that past offers can be "re-swarmed" and thus brought back.
It looks like the device was already resurrected once, as it was at the center of a swarm a few weeks ago, but the opportunity to bring it back again is still there. I don't know how many votes need to be cast for Dell to consider putting the deal out again, but your vote certainly can't hurt.[Dell Swarm UK] Thanks, Paul R!
