I have short term , medium and longer term plans
short term : I just bought a cheap anker BT keyboard and mouse for about £20 to play with workflows and see how I like it.
medium term : I use a MBP at work, and when I work from home I use a USB-C to HDMI adapter and USB-C charger. two separate cables. I'll get a hub with USB-C power in, HDMI out and some spare USB ports. That will be good for my work MBP, and I should be able to use exactly the same hub without chagnes to connect my ipad pro - it'll charge, and give me a second monitor out and access to USB accessories/ethernet.
longer term : I may replace my current PC keyboard/mouse with bluetooth multi-device versions. This will then let me use one KB/M with my home PC, ipad and work MBP. I already have a nice KB/M so this might be a year out, once I've had time to settle in with workflows etc.
Question on the hub - if it has a monitor out, will it always force that? Eg if I just want to charge my ipad but don't want the monitor switching on?
