People probably don't think about a poor person enough or they would come up with more solutions that benefit everybody.

Some only conceptualize scenarios that include those that are quite wealthy, whether intentional or not.

Even if you are not poor, one of the most respectable things you can do is to re-use and recycle rather than consume new.

For minimal cash outlay, surplus PC's can easily be found at zero cost which is naturally an unmatched bargain, compared to used monitors even as low as $10 each, unless you can get the monitors free also, but that's much more uncommon. Surplus keyboards are stacked up everywhere and being thrown away all the time too.

So it's really the monitors (and physical desk space) that's the limiting factor for aspiring low-cost operators. By a long shot.

It's been that way for years so by now with every multi-monitor workspace I have a PC for each monitor, even if I only run one of the PC's at a time usually. Each monitor also has at least two separate inputs which can be chosen from at any time and all the wiring is in place whether it is being actively used or not.

So between my office or home or an employment site a laptop used to be carried with me but now mainly collects dust except for "outreach" or distant travel these days. Laptop chargers still in each location so I didn't have to carry that as often.

Now it's usually only a miniPC (or sometimes two) that I carry for "full-strength" mobile deployment between locations. Chose miniPC's that run on the laptop chargers that were already at each desk. Even more convenient to carry than laptops.

Soon for the PC's that I have appropriately configured at each familiar location, I will only need to be carrying a bootable USB stick instead of either a miniPC or laptop :)

Might as well use the PC's that are already there too, along with the full-size monitors and keyboards ;)

Environment on a stick.

Not much different than the way you could put Windows XP on a bootable FAT32 Memorystick, then put the Memorystick into the Sony phone to utilize its remaining storage space the regular way. The cellphone folders don't interfere with the Windows folders. Then plug in the USB cord from the phone to a PC, boot the PC to USB and the phone acts like a bootable USB stick and your C: drive is the Windows volume on the phone's internal Memorystick.

This still works with Android and SD cards too.

It's good to have but it just ties up the phone and a separate USB stick is the real functional model.
