Routing power lines on top or bottom plane?

Noobie question incoming.
On a 2 layer board with a ground plane on the bottom, where do I put my power tracks (VIN, fuse, regulator I/O,...)? Is it ok to put them on the bottom also? This would leave the top layer for signal tracks only and result in a MUCH nicer layout. It's a DC, low voltage, low frequency, low everything board, nothing fancy going on.
I have read Dave's design primer. He suggests that you reserve a layer for power tracks and one for the ground plane on 4 layer boards, but I'd very much like to keep it at 2 layers. This whole PCB thing is messy enough as it is 
Is this a good idea?
