Suggestion: Ask manufacturers to STANDARD buid-in vga output. Almost every computerscreen has a vga input. Then you can use your smartphone/tablet for on the go and at home, for infotainment and for common office processing. The power of nowadays smartphones/tablets resembles that of desktops 5-10 years ago, but still good enough for common office tasks AND multimedia watching. Make it multiboot or debootstrap with Android/Linux(e.g. Ubuntu) for example. Then if you dont do heavy image/vidao/audio (design)processing, this migh be all you need: keyboard, mouse, screen (for at home) and a smartphone/tablet. 4-7 inch size device are probably the most practical for this purpose: a fairly large screen to use for OTG watching/working, but also light enough to carry around. A chance for Linux to breakthrough into OFFICE?
