I thought I'd be able to hold out a little longer, but after a crazy week of rehearsals where it seemed everyone was toting a new MacBook, and after waiting for what seemed like hours (minutes in reality) to open a fairly large Excel file, my patience finally ran out.
A few hours ago, I clicked "Make purchase" on a low-end MacBook Pro. I've been drooling over the updated MBPs ever since they were recently updated. With 2 GB of RAM and an LED backlit screen, it's a pretty sweet machine as is. I considered the mid-range MacBook, but once the RAM is bumped up to 2 GB, the difference in price to move up to a pro machine didn't seem like such a leap.
My only real qualms are a) that I like the smaller form factor of the MacBook, and b) it is my understanding that, like the old iBooks, they get better wifi reception than the MacBook Pros. However, the MPBs are also apparently better than the old PowerBooks in that regard, so we will see. I almost went back and changed my order, but I think the pro machine will serve me better in the long run.
Now I have to wait till it gets here.
