I was in the same boat...really determined to get a dope keyboard case. I am planning on using the iPad as a replacement for my old macbook so I knew a keyboard was essential. I initially bought this logitech when they had it for 40 bucks on launch day over at amazon...It looks like its 55 today, but if you go to the Kensington site and look at the item it states it will work with the new iPad as well

But after reading all the reviews and searching for other cases I kind of feel like this is keyboard case is kind of trash.
So I ended up going a totally different route, and am going to use this case for my apple wireless keyboard that also acts as a stand. For 30 bucks it seems far more reasonable and I like the look of it a lot. Plus it seems to work with almost any case so you could get a cheap case and wouldn't ever have to take it out when using the keyboard stand.
