Micro PC vs large Laptop vs large AIO tablet

[Wiser1]

Hello
I need to select a portable system with a large screen size (18" to 20"). It will be used for digital Eyecharts for vision screenings at various healthcare facilities. Thus the screen size and quality are important . Below are the systems I researched thus far. I am not tech savvy and would really appreciate the expert guidance from this great forum.

1. Dell XPS 18" AIO tablet (Saw this already-- it would work but I am not sure if sturdy enough to lug around?)

2.Lenovo Thinkcenter M83 Tiny Desktop + monitor

3. Dell Optiplex 9020 + monitor

4. NUC mini-PC + monitor

I'd like to keep weight down . Also would like good/best processor and speed, reliable for small business usage.

Please feel free to recommend other systems and/or configurations. All your advice and ideas are very welcomed.

Thanks so much in advance!

Well, it's hard to tell since you have stationary and mobile platforms. Which one would you prefer the most?

Are the micro-pc options 2, 3 and 4 above considered stationary? Could they not be used on mobile basis with a portable monitor and Wifi?

Thanks so much for your reply.

They could, but it would be a hassle having to hold the monitor, mouse and keyboard too. Plus it would need a external battery to be truly mobile.

A bit more info: when mobile, this system is only to be used for as a digital eyechart , (http://foresighteyes.com) that I control via a pre-setup ad hoc network with my iPhone and a dedicated app. Otherwise the system will not need to be mobile.
