I don't think it makes sense to go out and purchase the 640 now when the 645 is available. Unless saving a few dollars is a really big concern, in which case I'd suggest someone not even bother with the 640/645 and go with something like the 510 which is much more economically affordable.

I just can't see buying last year's model when the newer, better version is already out.

Just my 2 cents.

EVERYONE I WORK WITH USES IT. ALSO LIGHTWEIGHT AND EASY TO USE

Dude, I ordered this item SPECIFICALLY because I loved the idea of using the same charger as my 8700c - guess what? It's NOT the same! It is ANOTHER charger different from everything else which I'm gonna have to carry around. Thanks....

Yah...i was gonna weigh in on that for ya...but i got in on it too late =(

Just an FYI here:

Just because the peg fits the hole doesnt mean its compatible.

For instance using a v3 charger on your BB will cook the battery, proven fact.

Do yourselves a favor and just purchase the correct device-specific equipment. Dont mix and match your broke-ass Wal-Mart $5 accessory with a $500 device. Pay the extra couple bucks and get the real deal.

OK, given that, I have 2 questions:

1. Are there any BT headsets that DO use the same BB charger connection?

2. Which of the leading BT headsets lasts the longest - i.e. has the longest battery life between required charges?

Thanks!

Another dullard chiming in. I was set to head out to Best Buy to pick up the 640 before reading Igreenberg's post. The 645's not yet avilable in Ontario at Best Buy. Worth a wait. Second choice would be the Moto 700, based upon CNET User Reviews, and opinions expressed here.
