Most pumps fit beside the water bottle, which makes more sense to me.... Rather than carry an empty bottle just to carry a pump. Plus the Topeak's mount is so cool, its a bit Ghetto to have a pump like that rattling around in an empty bottle.

If I carried water in it then it would by definition NOT be a 'spare water bottle'. I would guess that by June/July it will no longer be quite as dispensible. But when it's 35º - like my 3+ hour ride this AM - I really don't drink much. And I felt great. Intervals.
Cue the 'you really have to drink more' rant. At least I won't drink myself to DEATH like some of these slow marathon runners. And it has been a VERY long time since I bonked on a ride.
