I did Business Class 777 from Melbourne to LA earlier in the year (yay business trips over 9 hours!). And ...
Yes. Really, yes. I mean, if you have to travel, get someone else to pay business class for you. (I can't see any difference between first class & business these days.) The Platinum lounge at O'Hare was pretty darned cool too.
Only problem? The sleeping pods are shaped like almonds, head at the round end, and designed for someone up to 5'11". Me, 6'0.5", and my toes kept jamming in the pointy end.
