There are a small number of phones supporting DisplayPort alternate mode so they can be docked to monitors and keyboards. And the performance is not at all bad any more, check https://browser.geekbench.com/android_devices/839 vs https://browser.geekbench.com/processors/2294 or https://browser.geekbench.com/processors/763 Basically, the fastest Android now caught up with Haswell desktop chips which is a pretty impressive feat. While RAM is not plentiful, top phones are now 8GB which is not bad at all. The real problem is more in storage, compare https://www.samsung.com/semiconductor/insights/tech-trends/e... to the SN520 -- I picked the SN520 because it's available in a 2230 physical format so the physical advantage is smaller but of course still existent, anyways: https://www.sandisk.com/content/dam/sandisk-main/en_us/asset... the sequential speed is five times faster, IOPS closer to ten. (I also picked the SN520 because I am using a 2242 version of it now.)
