Oh, yea definitely a laptop! I don’t use desktops anymore.
Laptop ==> Desktop
Mobile ==> Stationary
90 Watts ==> 600 Watts
No Battery Backup (UPS*) ==> Need UPS
17" X 12" Footprint ==> 24" X 8" (Tower) + 19" X 6" (Monitor) + Keyboard + Mouse + Speakers……
UPS: Universal Power Supply, if I remember correctly.
Footprint: The area of the ground covered by the hardware, ie a laptop covers the area under the keyboard portion of the unit, while a tower has to also use up area for the monitor, keyboard, speakers, laptop, etc, etc, etc.
