I've been converted to the "add peripherals" side, personally. The standards are developed enough and the selection is broad enough to dial in whatever balance of price, portability, ergonomics and device features is desired - at the extreme end, a USB OTG hub connecting your full size mechanical keyboard, MMO mouse, graphics tablet, game controllers, and flash drives, and at the other, pocket folding Bluetooth keyboards and mini mice. It turns a phone or tablet into "just a screen" - a viable entry level workstation only held back by software and processing capacity.
