Keep your powder dry for a few days more.. I sense you have have a mild case of buyers fever, so cool it
The MacBook Pro is, according to one or two friends that have acquired one, a great machine. One drawback of early adoption of MacIntel machines however, is that any pro apps you run on a regular basis (i.e. heavy Photoshop work, Dreamweaver, Final Cut etc.) will be slightly slower than the older G5 equivalents, as they will be running in emulation mode (Rosetta) until Adobe et al produce 'Universal Binary' versions of their apps to take advantage of the Core Duo processors. This is unlikely to happen until the end of the year, although a good number of smaller vendors and shareware developers to have 'gone universal' now.
Due to my 6-month old G5 iMac dying on me last week
(fried logic board anyone?), Apple have given me a spanking new Core Duo iMac as a replacement and I have to say, apart from the above, it really is a very zippy and quiet machine indeed. The Pro apps' performance is 'liveable' but yes, slightly slower and the rest is much quicker. The machine is heaps quieter too. So I'd say if you're going to be using an Intel machine for general or business use, using mainly, say, Office, Safari, Mail and the iLife apps, you won't be disappointed at all. The same will probably go for the iBook too, if an Intel version of that is announced next week.
