Apple Files Patent Infringement Suit Over 'Knock-Off' Power Adapters

Sorry then. I should have said that "all of the Lenovo adapters that I've used and seen have been two prong".

Ahh, ok.
The charger a dell laptop I had came with was two pronged. I replaced it and the new one was 3 pronged. Maybe it's a recent change.
But there are positive reviews there of other Apple products (equally trivial ones like keyboards). That means its unlikely that everybody coming to give a review is coming to gripe. If it had been posts in a technical support forum you would have a case, but these are reviews and aren't by their nature self selective as you put it, or there would be no positive reviews.
My poin is the ratio of bad to good reviews is not the ratio of bad to good adapters. Obviously ther will be outlier positives.
It is grounded.
The grounding connection is an integral part of the circular metal tab that secures the three-prong power cord or duck head to the transformer.
I think it would be great if people looked at what they were criticizing before throwing out accusations. Esp. the Windows users who seem to have never used a MacBook.
Irony
Does anyone else think it ironic that this thread about apple suing the knock-off power adapter manufacturer is just below the thread about apple taking half of the pc industries profits?
Yet the Mac costs on average 3 times more.
i'm not a troll, I've purchased over 25 mac products since the 90's and one pc.
I think Apple could do a little less nickel and dime.

So when a company makes an obscene amount of money because they offer a better, more desirable product that people are buying, they should then go easy on patent issues?
When you start your own company feel free to give your IP rights away. Since you don't know that revenue (as discussed in the article) is not the same as profits, I don't think your company will last very long.
So are you implying that Apple shouldn't defend their patents, or that Apple should charge less for its products?
Fair enough.
OTOH, here is a link to the thinking of the day (via gruber) back when Amelio agreed to buy NeXT: http://money.cnn.com/magazines/fortune/fortune_archive/1997/02/03/221517/index.htm
Interesting excerpts, FTA:

Of course the most amusing part is where Alsop pitches BeOS (and ean-Louis Gassee) over NeXT (and Jobs) as the viable source for the new Mac OS.
Probably best for all involved if Alsop stays in publishing and out of the venture capital business.

BeOS had some very interesting properties and features. For a consumer OS, it was superior to NeXT in many ways (and inferior in others). Sad to see that it's stagnated all these many years.
Do you really think there isn't?? That the metal grounding pin in the adapter is there just for kicks?

In the small channel either side is metal which makes a connection with the earthing pin on the MagSafe power brick. This earths the MagSafe and MacBook Pro.
sorry if i dont have every revision of every mac product to date but this is why i posted my original comment. go to this apple store link, there is only 2 prongs and no ground
http://store.apple.com/us/product/MA538LL/B?fnode=MTY1NDEwMQ&mco=MTA4NDE2NDY
also with the 85W i dont see a ground either

also check the rating from Apple users that purchased the adapter, 2/5 stars! thats absurd for a Genuine product.

see my quote above i looked at the apple store.
As has already been pointed out, on ALL of these adapters, you have two choices - the two prong thing you see in the pictures, or the three-prong cable that replaces that little two prong thing. The box comes with both. People tend to use the two prong thing mostly when traveling, as it takes less space to carry than the three prong (which is attached to a long cable).
The three prong cable is grounded and connected to the disc on the brick.
