A do it all laptop
I really have nothing against Linux. It's just that there is virtually nothing you can actually on Linux that you can't do on OS X.
Now let's see, I can get everything I'll ever need for hardcore *nix either from the OS X distribution or from fink. Fink is built on top of the Debian Package manager.
OS X is a main branch of the XFree86 project. I can run X11 by itself and the machine looks just like a Linux box. I can run X11 in rooted mode and toggle back and forth between X11 and the Aqua interface in a few hundred milliseconds. I can also run X11 rootless and interleave X11 windows and Aqua windows as I please. While I'm doing that I can be editing video with sophisticated software like Final Cut Pro or if I just want to whip something out quickly I can use iMovie (so can my grandmother). iTunes keeps all my mp3's in order and accessible or synced with my iPod. I love digital photography. I've got thousands of images organized and easy to browse. This is all made possible from iPhoto. Gimp ain't bad, but I doubt you'll find anybody who earns their living as a digital photographer that doesn't use Photoshop. If I need a "FULLY compatible MS Word" processor I've got it. When I'd rather "keep my hands and soul clean" I've got options. Likewise as a medical researcher, lately many of the conferences I attend won't even let the presenters use slides anymore. You must have a PowerPoint compatible file.
The new Quartz Extreme compositing engine is the most advanced screen management system available on any mainstream computer. It handles PDF and OpenGL together seamlessly and hands most of the heavy lifting off to the graphics chip for processing leaving the processor free for other tasks.
If I walk into a *nix installation and want to "join the crowd" I can fit right in. I've got ssh, NFS, NIS, LDAP, ipSEC, PPTP and just about any other bit of alphabet soup you care to name. As of OS X 10.2, the whole printing system is sitting on CUPS. For the uninitiated, CUPS stands for Common UNIX Printing System. I can (heaven forbid) even make connections (client or server) with Windows networks. I've got Apache for web serving and sendmail for mail duties although if I ever really need mail facilities I'd rip out sendmail and replace it with PostFix. I can communicate with 802.11 wireless networks and can talk to Bluetooth devices. I can browse for network devices and functionality on an IP network with Rendezvous (an open standard).
When I need to work, I've got all the tools I could possibly need. When I want to play or "prove my manhood" by getting down and dirty with *nix I can do it. Or I can do it both at the same time.
All of this functionality is on a laptop about an inch thick. Can you show me any Linux based laptop that can manage all these jobs? Linux is fine but for a universal, portable, do anything, connect to anything or anywhere system OS X sure floats my boat.
