This model is $100 more than the similar model, but states it is the "latest". Does anyone know the differences?

Check the number of heaters, also whether they are Ceramic Heater or Carbon Fiber Heater. The Carbon fiber heater is higher, which this one has. You might want to check the size also. I didn't want the windows which is what I think you are comparing it too.

I'm looking to buy one. Such a good question but no one seems to know the answer. :(update: I think they are the same except one is more cheaply built. But which one?? Who knows...could be the higher priced one!

I think this is the newer model. My sister in law recommended it and this is the one she had shown me to purchase.

This one is prettier! I have the 650 but I don't have the 640 so I can't really make a comment if whether they have the near exact specifications like you stated. I always thought the bigger the model number the better. If I have time I might stop by a Best Buy to play around with it. If you can get the 650 for $900 free shipping on amazon, it's still a good deal. But if you're fortunate enough to live in a state that has a brick and mortar Fry's Electronics, sometimes they have it on sale for $700 plus tax. Their price is different though via frys dot com. You can wait around until Thanksgiving but I don't think it's gonna drop to less than $800 on a 1-day sale. This one is prettier!

I cant answer 100%, because I read in misc forums that new version uses same numbers as the old.What I can answer is "THIS version when I bought it, is not the new versions".

The model at B&H; is the new version. The difference is only that it works with iPhones. There is no reason Amazon should be selling it for way over the recommended price. I imagine they are trying to 'encourage' people to clear their stock of the old model before they drop the price, which is REALLY annoying.

Because it is a cheap machine that is all about hype and marketing. Pls avoid. It is 2-3 times more expensive than all the others and not worth $100!

I don't know but I imagine you might find it in researching it; typically, unless the price difference is huge I go with the latest technology; this may not be a situation where it's significant but might be worth looking into; good luck; it's a great little unit; I've been extremely pleased!

the only thing I can tell is that the WD-60C9 is the updated version. I've had my eye on this 60" for the past year thru Amazon, QVC, & Best Buy. BEST BUY HAS IT (the wd60c9) RIGHT NOW FOR $799 OMG OMG OMG!

I saw that too...I'm not sure what that's about. I don't think it's any different than the other 901s except for the color and other minor differences (keyboards feel different between the black and white models). I'd also like to know what is making it $619 when the other 901s are $275...

they're both the same. just different prices. go for the less expensive. i have this one and paid only $262.00.

I'll second that. I would buy it right now if this model included the $100 Amazon coupon. Otherwise, it's a little expensive.

I think the difference is that the new model probably has better internal components. Improvements to models are usually never stated, only new features if any.

I recall when I bought my 9001 a newer version was also available. The newer one didn't seem to be any better than mine other than it was a slightly better looking unit. I don't remember other details other than aesthetics. I love my 9001.

I don't know what they mean by "old version"...pictured is the same V2 we purchased about six years ago and also the same unit currently being sold at B&H.; Unless there's been some software or firmware update that I'm not aware, I think it's the same beast it's always been.

I don't see any difference....looks like that would be the place to buy it. I got it in Sept from amazon and paid 90 bucks. I'm happy with it but I also don't use it much.

Not really sure... I have the SR model which seems a bit cheaper. The SRW may have some tweaks in design and features but otherwise, they seem to be about the same.
