Way too expensive to be worth it for me, but I can see people who deal with large amounts of Bitcoin as part of their jobs not being too bothered by the price.
Something to remember is that Trezor has been around for a year now and well proven. At only $99 less than half the price of KeepKey and Trezor works with Mycelium on your Android phone. Trezor looks like a bargain now in comparison. Even the new standalone Case hardware wallet is only $199.
