I love the promise of this machine but it has been a bumpy start. The most disappointing event has been Microsoft positively affirming to me that the touch keyboard for the pro 4 does not support the Microsoft wireless adapter and that there is no known solution for the foreseeable future. For my needs, this is almost a deal breaker. Moreover, the tech person admitted with chagrin that the advertising is false / misleading. Also, if someone can tell me how to start a new thread in one of the other forum locations I would appreciate it. Thank you.
