i have a macro lens, but mounting and dismounting it is a pain! i mostly use it for ultra dark shots/fish-eye to fit very high objects/buildings in the frame, in the dark...
and i make sure that i have a decent inter-changeable zoom-lens for my camera. but not too big either, or i just wont lug it around...
for macros, it really helps if you have a zoom lens. i have a digital zoom too in addition - to get an even closer shot. but what often happens, my camera due to light or other factors has a difficulty focusing in full zoom + digital zoom mode. IF your camera can get a good resolution pic - somewhere in the 3.5-4.2 meg area, you actually don't need to go to macro (where you'll get a very shallow depth-of-field), just take a pic close enough but not super close. you can then crop the image and enlarge it without loosing resolution - and there you'll have your pic AND macro too!
so try to stay back a little and then enlarge and crop on the computer to see if your camera can do it.
