I had a 2015 MacBook Pro which I liked much more, but it was my personal property and my company insisted on buying me one. Besides being faster, the 2018 seems like a step backwards:
1) It's been rebooting itself lately. My 2015 never did that. But maybe it's a software issue... I don't know yet.
2) The keyboard has already had problems. But maybe it was just once... I don't know yet
3) The touchbar thing is a big pain. I don't like it; if I'm holding the laptop in my hand, it's easy to press one of the buttons accidentally, because they aren't raised. What's more, I set mine up to be a consistent set of buttons: brightness, play/pause/mute/volume. But unlike the fixed buttons, in this setup, the play/pause won't work with iTunes unless iTunes is the active application. So it's a step backwards, but not a deal-breaker.
The deal-breaker for me, by far, is the USB Type-C connectivity. I don't care that they have USB Type-C; in and of itself, it's an upgrade. But they took away EVERY other port. So if somebody gives you a USB stick to copy some files... you need a dongle. If you go to a conference room to play a video via HDMI... you need a dongle. EVERYTHING needs a dongle. To use the same DisplayPort monitor I used before, I need a new cable. I've NEVER had such a poor laptop experience. My laptop bag is FULL of stupid little dongles and adapters. If I want to charge my iPhone, it's one cable, if I want to attach it to my laptop, it's a different cable, or a dongle... ABSOLUTELY NOTHING YOU OWN can be connected to this laptop unless you buy a dongle. That's not so bad, except that I'm a very mobile person; I present in conference rooms, at customers' sites, etc... and carrying all the stupid cables and plugging one thing into another is just stupid. Had I known how inconvenient this laptop is, I would not have accepted it.
They changed the power supply to USB Type-C. First, this means no more MagSafe, which was a FAR FAR FAR better power supply connector. What's more, USB Type-C cable is very thick, and so the new power adapters have cords which you cannot wrap around the power supply, like you could with MagSafe. There are vendors on Amazon which sell MagSafe to USB Type-C adapters, so you can use your old MagSafe power adapters, but, once again, it's another dongle, and it's minuscule and very easily lost, as are the USB Type-A to Type-C converters for memory sticks.
