Got mine in today and I have been using them all night. @Walkerstop has some great first impressions in his thread.
To me, they do have a very short and sharp bump that I kind of like, especially after all the big round ones we have had recently. There are some of the aspects that I like from box clickies in them, but not extreme. Barring a few issues I am hoping to investigate further with more data, they are an interesting feeling switch.
