I would avoid them
Thing is, to use them in recording applications they are presenting themselves as an input only USB audio device. Since they don't offer output you're stuck with monitoring through another soundcard. Now if you use ASIO drivers for your soundcard there is a problem 'cause the ASIO protocol does only permit the use of one driver at a time. So how do you monitor what you're recording? The Samson mic comes with an ASIO driver, the Blue one seemingly not, which means it uses the standard windows usb audio driver, which has a high latency, making realtime monitoring impossible (no fun singing while hearing everything with a 500 msec delay

. At least that's my understanding from what I've read about them, so far. If anyone has different experience please correct me.
Also I personally find a Microphone that needs a computer to work at all, not a good thing.
Better get a cheap conventional Condenser and a small preamp or sound interface with preamp. Maybe a little less convenient to carry around but a better investment in the long run, me thinks.
