It is a fine machine, but very high-end consumer oriented. I use my mac laptops for programming, video editing, and running music applications. I actually DO have multiple batteries, maxed-out ram and use multiple firewire and USB accessories. I was quite disappointed that there were no updates to the "pro" laptop line. Perhaps this market (the "creative mobile professional market") is a loser for apple and they want to get out of that business. Also, I purchased a MacBook when they first came out, and had numerous problems with the battery and power supply. Thus, the lack of replaceable battery makes me nervous.
