I'm afraid that I am about to give the opposite advice!!! IMO there are two opposing things that you need to consider:
1) Do you want to continue to use Logic?
2) Do you want to continue to use a PC?
If the answer to 1) is yes, then you have no choice, you must get a Mac. However if the answer to 2) is yes (and this is more important to you than using Logic), then forget Macs and start looking for another sequencer. I would say that all sequencers have moved on so much since your version of Logic that the learning curves will be largish on any system, and when you add it to learning how to use a Mac I doubt that it would make much difference.
The advantage of using a Mac is the increased access to RAM, but if you are using a laptop this may not make any difference to you. Apart from that, there is no advantage to using a Mac. PCs are (I'm afraid) just faster, and PC laptops, in particular, smoke anything that Apple has to offer. Also do consider that the new MacIntels are very new and there are a lot of applications that currently won't run on them.
Next thing to consider. Once Vista is up and running Apple Mac will really be legacy technology, As far as I am aware they don't even have a 64bit OS in the pipeline, and it is unlikely that they will do so for some time. When you compare current systems for PC and Mac with the thought of 16 processor PCs with up to 128Gb RAM you will understand why Vista is so important for those of us who run out of RAM long before anything else.
Regarding the ease of use, even if you had never used a PC or a Mac before I don't think that there is much difference these days. Look at this forum and see which platform is having the most problems.....! Remember also that there are proportionally less Mac users, and most of them here are using Logic. I would say that currently the PC platform for VI is far more stable and in terms of upgrading to more powerful systems there is a clearly visible path; not so in Mac land.
