The waiting time is horrendous though. Mine arrived 8 months after I purchased it but beyond that, those are absolutely great. I stopped carrying a laptop in my backpack, just one of those with an additional expansion board and an HDMI port. My work involves a ton of data which I can't fit into memory so in all cases, my computer is just a terminal to a large server somewhere. So Clockwork ticks all the boxes for me. The one thing I wish they had thought about is an easy access to the CM and be able to swap them for different use cases: when I want to preserve battery and speed is not a big deal - cm5. When I want some additional power - pull out the cm4 and toss in a 5 instead.
I wish there was access to swap the batteries without having to unscrew the back plate. I got mine after the long waiting period and was initially excited but eventually it became a dust collector as I don't have a usecase for it. It is also quite heavy to lug around in a pocket or something like that.
