Personally I find myself almost always using my laptop in one of 3 ways:
- on my lap, in front of the TV, on dining table, etc. - no dongles or wires
- away from my desk, but working - 1 wire for charger (maybe), 1 dongle for wireless full size keyboard and wireless mouse
- at my desk - 2 wires for monitors, 1 wire for charger, 1 wire for speakers, 1 wire for USB hub... then from that, wires for keyboard and mouse and USB hard drive and all the rest
It's not obvious to me that USB-C is going to make much of a difference to this one way or another. The lack of a Magsafe-type magnetic connector is a backwards step, in my view, and I can't say I'm overjoyed, in fact I'm quite the opposite, at the prospect of having to having to buy a whole new set of hubs, chargers and adapters. But I don't think my desk will be any more or less messier afterwards, and it's not like they're doing a Macbook and giving you only one port (assuming all 4 ports are equal of course).
