I will be replacing my old PPC Mini with something more upgradeable and generally better, maybe by end of this year. An Intel Mini would be an improvement, of course, but it's too much of a pain to upgrade over time and i think I could do a little better. Not mac pro better, but a little better. My needs are fairly modest. Would it make sense for me to buy a MacBook and connect it to my monitor and peripherals for use as my desktop Mac? I already have a 12" PPC iBook that is nice and portable for my road unit, but if it ever died, it would be great to know I could just disconnect my "desktop" computer and go mobile with it.
