I've been developing against 8.2 for months without a single 8.2
specific problem. I run both linux and windows in high load
environments (not so much windows these days tho). I'm going to go
against the grain here and say go for it: yes, it is faster. It's up
to you to determine a test period long enough to build up a trust
level.

possible downsides:
* catalog changes during beta period. (dump/reload to update to 8.2
proper, etc).
* last minute feature change. note recent small change in insert
returning as an example.
* risk of undiscovered bug

ideally, i'd develop/test vs. 8.2 beta, and switch production system
at 8.2 release.
