One of the differences between KBC poker and KBT pure I noticed: the size of right shift key. The one on KBT pure is 2/3 the size of KBC's, which seems to be an improvement. Of course, layered functions are also different. I hope there will be a newer version providing the capability of user-defined key mappings stored in nvram.
