So I got an HHKB Lite in today...
Pros:
1)It's tiny! (see image below of my G15 eating it)
2)Replacing CAPLOCK with Control is surprisingly easy to get used to and once you do you realize it's far superior.
3)There is a dip switch on the keyboard so you can change a few of the default keys around. For example you can change the delete key (see image) to a backspace and the strange diamond key to alt.
4)According to the spec it's capable of registering 10 different keys down at once. I only tested it w/ 5 keys down at once and it worked flawlessly.
Cons:
1)The force required to press a key is very tough and it's almost linear in toughness. Keys also have a very limited travel compared to any other keyboard I've used (except for laptop keyboards)
2)By default the key above Enter is a Delete key and to make it a backspace you press the Fn key + delete and it turns into a backspace. However, if you're like me and prefer a backspace key to be above the Enter you can flip a switch on the keyboard but Fn+backspace does not turn into delete like you would hope.
I.E.
Dip switch 3 off:
delete key deletes the character to the right of the cursor
Fn + delete key deletes the character to the left of the cursor
Dip switch 3 on:
delete key deletes the character to the left of the cursor
Fn + delete key deletes the character to the left of the cursor (I would have expected it to delete the character to the right)
3) Moving the |\ key has proven to be extremely difficult to deal with. My pinky cant really reach beyond the += key.
Potential Cons:
1) The Fn key does not appear to be sent to the computer at all, I.E. windows doesn't pick up a keyevent when you press the Fn key. I'm not 100% on this as I don't know of a reliable way to test this. No game was capable of binding to it and a quick and w/ a quick and dirty Java program I didn't get a keyevent.
The stiff crappy feel of the keys is just a complete deal breaker for me. If it wasn't for the horrible feeling keys I would probably give this keyboard a 9/10 rating as I would probably just use Auto hotkey or some other tool to rebind |\ key to something else.
As for how bad the keys are (to me and my friend) I did a blind key feel test between this keyboard and an old $9 gateway keyboard, both myself and my friend choose the gateway keyboard as having better feeling keys. I didn't do the test vs my G15 as both of us use that keyboard as our primary keyboard so we're too familiar w/ it and I know we both would have chosen it.

The ancient gateway keyboard (no i never bought a gateway computer i got the keyboard from directron.com i have no idea why they were selling them lol)
