Got mine last Friday from MacConnection
Received mine (2GHZ, ordered as 1.83) with 1GB memory) on 2/24 via DHL - shipped early last week. Per MacConnection, they got an initial shipment of 300 units, most if not all were presold. I ordered mine in late January and was at around 100 on the list. Note that they have no sales tax in California, and are actually offering a rebate (or so they say, we'll see if they honor it) and offer free shipping, so it was the best deal going.
As for the system itself, better than expected. I run MS-Office alot in my work, and performance is good or better than my old 1GHZ 17" Powerbook, and that's with Rosetta emulation to support the MS Office stuff. So far, very stable, and the native apps run like a bat. Battery life appears to be around 3.5-4 Hours, but I'm not sure I've really conditioned the battery properly - didn't really want it to go all the way down to forced sleep.
The thing that was really amazing was how good a job they've done on the upgrade tool. I plugged in my old 17" powerbook in Target Disk Mode, and 2 hours later, all 44 GB of files, software, etc. was copied over, and I was up and running as if I was still on my old machine. MS-Office ran without a hitch, all my bookmarks were preserved in Safari and Netscape, the passwords, etc. on my keychain were intact (although you have to reconfirm access permission on first usage). I thought that I was going to need to reinstall stuff, redo passwords, reset up my networks, etc. Even all the locations were copied over, along with all the IP settings, etc. Pretty cool - my PC-based colleagues were pretty envious - apparently it's a nightmare on Windows XP.
My big issue now is with a PC emulator - I'd been running Virtual PC, but obviously Microsoft is dragging their feet - best bet looks like iEmulator, supposed to ship mid March per their tech support - has anybody tried other alternatives?
Sorry about length of post - lots of stuff to cover,
