I like that it can be used with our existing system so we don't have to purchase another piece of hardware or hire new employees just because they're using something else now! We've been able use this since day one when everyone was still at their old jobs until yesterday (they had switched companies) - no problems here!! It's not super easy/convenient but if you are already familiar then there shouldn't really any issues either way as far as implementation goes. Just make sure your IT department has time set aside during deployment days etc. Also try out multiple different options in order to see what works best for YOU before making an even bigger decision than needed about which option will work well within YOUR organization AND budget BEFORE committing yourself 100%.
