I've had my Nexus One since Feb. Best phone I've yet owned, and I've owned a lot. The best part about the N1 is that it's the basic Android install, there's no extra stuff to slow it down. Which means that if I want a new homescreen, I just go to the market and download Launcher Pro, or whatever homescreen/launcher I want. I dabbled a bit in rooting and custom ROM's, I might still flash Cyanogen, but the stock experience is good enough. There may come a day when Google no longer supports OS updates to the N1, but with everything unlocked I know I can still try them out.
Then there's being on the bleeding edge of Android, I was using the test build for a month before the official 2.2 update, which will have been out for 2 months before any other phone gets it. Flash is really nice,
most webgames are now totally playable from my phone, which gives me about as many good games as any other mobile OS does (not to drag this into a competition, just saying ports of web-based flash games are a staple of the Apple App Store. Locally stored versions aren't necessarily a bad thing.).
Am I sad to see it gone from consumer shelves? Meh. Not really, I already got mine. If anyone wants one in the future, they'd just have to register as an Android developer ($25 fee) and buy there. There's some B&M places that sell it, and rumor has it Amazon might pick it up. For our foreign friends, Vodafone won't stop selling it.
There was something really cool about actually buying something from Google. You usually think of it as a provider of free services (yeah, you pay for it with information, not the same thing, you don't get an invoice for that).
From "How Has Your Smartphone/iPod Touch (Portable WWW Device) Changed Life?" My complete list of cellphones I've owned, this is over about 4 years, N1 beats them all:

HTC Touch Pro (Windows Mobile 6.1/6.5)
Motorola KRZR K1 (dumbphone, I was feeling retro and bought one for $30 unlocked)

iPhone 3G (iOS 2.x)
Palm Centro (PalmOS Garnet)
HTC Tilt (Windows Mobile 6.0/6.1)
Motorola Q9h (Windows Mobile 6)
Blackberry Pearl 8100 (I HATE Blackberries)
Nokia E62 (Symbian 2nd Ed, what a giant hunk of crap that thing was)

Samsung BlackJack (Windows Mobile 5/6.0)
Motorola KRZR K1m (man that was a sexy phone for the time, decent MP3 player, oddly enough was faster and had better software than the K1 I bought years later)
