Recently I purchased the Airhawk.
If you ride motorcycles (or even just sit still for long periods of time) This is really cool. While riding, anything over about an hour or so starts to get very uncomfortable. With the Airhawk on the seat, its still comfortable after 3 or 4 hours (and probably longer but I’ve not been on the bike for that long yet).
This would have won the ‘coolest thing ever award’ for this year but the remote just beat it.
