It is quite a dilemma isn't it?

I almost got myself the mac mini, but on second thought, I would wait a little longer for Leopard to release first.

The 24" imac is very tempting too, great display, neat machine, what a superb industrial design.

On the other hand, if you already have some cool hardware like big LCD screen & etc, mac mini would be a wiser choice, don't forget the 24" imac would cost more than double the cost of mac mini.

If not mistaken, I did saw 30" ACD attached to a mac mini in LYP apple store a while back.

Of course 24" imac will be ideal, mac mini is not too shabby either for web designing and stuffs.
