ThinkPad X41 (ultrabase with 320gb hard drive) and Echo Indigo IO (great 24/96 cardbus sound card that has fine headphone amp built in) for travel & music
ThinkPad T43p as primary machine with 15" 1600x1200 screen (am I the only one who prefers this to the widescreen 15.4 deals?)
Powerbook Pismo(retired) and a 12" iBook G4 for writing. I was loaned a macbook for awhile and I think it's one amazing package of power for the size and price. Multi-boot dual core beauty for a cheap price!
I prefer apple lappys infinitely to windows for audio playback for the native bit-perfect no hassel transport ability (especially powerful with itunes, or simple and clean with cog) and then you have Max which is very valuble for ripping and or converting between formats.
The only reason I switch to thinkpad is because the ultrabase or ultrabay way of carrying a second hard drive is preferred to those inelegant external drives. Having your music on a high capacity second drive is convinient and easy to upgrade hard drives (500gb is going to replace the 320 soon)
Now you don't have to worry about plugging in usb cables and whatnot and you have an all in one machine with no wires except your headphone cable connecting to the echo audio card
For iems and efficient cans I greatly prefer the high rez echo card to any usb dacamp deal (yes even my beloved pico).
Besides that giant blurb about mobile computing audio, thinkpads have great keyboards (don't underestimate this. Their keyboards are for real work) and yea you can run osx on them (barely) Almost all of them come with the nifty thinklight(also more useful than you can imagine at first) and the fingerprint reader(finger slide, not the less secure finger stamp type) is just smart, even if all it does is save you a few moments of typing awkward passwords. Macbooks the choice overall because since you can run windows on them there's no excuse not to get one unless you think they are "fruity." All in all, it's a tossup between
macbook or
thinkpad or both

btw if you get yourself a "lenovo" thinkpad (which I'm sure you will get unless you get a macbook or mbp!) go on ebay and buy a couple of "ibm thinkpad" stickers and put them over the lenovo
