Technically day five isn't over yet, but with just one session and a taxi ride remaining I doubt I'm going to get anything prematurely wrong here. In fact, I'm no longer entirely sure that I'll remain awake through the rest of the day so even if something entirely different does happen (still haven't heard anything about IXKit this millennium) I expect I'd miss it.
Planning an east-bound flight is always difficult, because an 11-hour flight through eight time zones "takes" 19 hours. So if I sleep on the plane I'll wake up in the middle of the afternoon UK time, and going back to sleep at newly-local night-time might be complicated. Conversely if I don't sleep on the plane then I won't be going to sleep until at least 9am currently-local time, for a total of about 28 hours uptime. I was just talking to someone who recommended fasting, I'm not sure whether it's worth going through that hardship for an unverified theory (stuff all of that "in the name of science" crap). The other option would be to go into work 3pm-11pm for the beginning of the week, I'm not sure everyone else will appreciate having their meetings moved to the middle of the night and I don't think the canteen's open that late either ;-).
Still, of the three WWDCs I've been to this is definitely in the top ten list of interesting and exciting WWDCs. There definitely still are fellow NeXT fans in the woodwork (actually, *tap* *tap* I think it's gypsum board) who worm their way out during these events, I guess that most have no motivation not to be working on Cocoa. Actually, I don't recall having seen Andrew Stone this week, and I know of a couple of other guys who aren't here, but have definitely managed to gain some traction for the phrase "NeXTSTEP Mobile ;-)
