I don't understand why boot-up time is an issue for a laptop. I cannot remember the last time I rebooted my MBP; the only time it gets switched off is when I have to install security updates which is pretty rare.
Using an Air as your main development machine seems odd to me - I want a large display so that I can read docs/papers and have emacs open at the same time. I also want good separation between screen and keyboard for maintaining decent posture. I hate to use a laptop as my main machine for exactly that reason. My main development machine doesn't get picked up and moved around enough (at all?) to be worth using a high end laptop. For the same price as the machine at the top of the page you could buy a decent desktop and a 13" Macbook and lunch, I guess.
I reboot my MBP every few days. It gets sluggish if I don't. I'd love to know why you don't have to and I do! I suspect it is the heavy amount of stuff I have running compared to my available RAM? Anyone else have this issue?
Basically I have 4GB of RAM (on the latest MBP) and regularly run: Netbeans IDE, Safari (and a bunch of tabs), Firefox (ditto on the tabs), an FTP client, a Subversion client, iChat, Mail, a notes app, alarm clock, Dropbox, Evernote, terminal, one other text editor (MacVim or Textwrangler), Photoshop, MS Word, a clipboard app and sometimes VirtualBox running Windows XP (with 1GB of RAM assigned).
The killers seem to be Netbeans and VirtualBox. Once I have those both going I know I'm in for a reboot before too long.
I assume it's just a RAM issue but it is annoying that 4GB isn't "enough" (assuming I'm correct about why I have to reboot).

Did you check top? free? You should be able to see what's eating your machine after a few days of uptime.
That sounds like a herculean load. Everythign running at once?
Does shutting down all the applications and re-opening them help? Something's got to be eating all of your RAM, and it's hard to guess without seeing top/Activity Monitor.

Word. For me, every Mac has been instant-on for years. I open the lid or hit the power button (iMac), and the machine is up and running (from sleep) in a second or two.
One scenario that immediately comes to mind is frequent flyers. I note this since I just took a series of flights a few days ago. Say you want to be productive during your six hour red-eye flight. That involves several repetitions of "we are now preparing to descend and land, please turn off all electronic devices at this time." If you're a business user who goes through this on a regular basis, a long boot time could indeed get annoying in a hurry.
I generally just put the laptop to sleep by closing the lid. Macs are generally quite happy about that - the superb power management is one of the major selling points.
On a normal flight "switch off electronics while landing" happens once. If you think otherwise you have failed at flying (sorry, couldn't resist re-using your phrase there).
