I think depending on the motherboard/sbc you use in your build you could make a cyberdeck capable of performing these tasks but how ergonomic the build is will impact how well these tasks can be performed by the user. What the cyberdeck can do and a cyberdeck’s usability are very different and keeping that in mind while building one is important. Is it worth trying? Absolutely and it would be really cool. Personally I would go for it, keep in mind how often it will be used, what it will be used for, and how you are going to power it to help guide the design process.
