Using Cubase and Microsoft Surface in a complete touchscreen interface

Hi to all,
I’m intentioned to use a Surface Pro 7 I5 8G 256 that i’m testing and experiencing as a great machine, to sketch ideas to rework and finalize then with a Pc with all the classic connections n hardware.
Anyone is using a Surface just in the Tablet version (almost like an Ipad)?
I feel great potential even if at the same time i’m encountering some difficulties using it without a mouse a keyboard and a midi external input source. An Ipad is tremendous immediate in comparison but less expandible and without the possibility to run a Cubase comlex project that you can work on in recent versions.
