Hi, Thanks for your report. Yesterday I took the plunge to Windows 10 as well (starting right off with build 1511). It worked like a charm. All special hardware devices (fingerprint sensor, LTE module, pen, touch etc.) are supported. I did not have to enter any PIN for the fingerprint sensor. Hopefully it stays like that... I actived the option to postpone updates in order to have better control what will be installed in the future (hopefully...).
