I went a little wild in 2018. Due to some changes in the American tax code and some additional restrictions on independent contractor income, I was compelled to get some money out the door before the end of the year on business-related expenses, so I remade my home office:
I got a new 21.5" imac, Yeti mic, autonomous sit-stand desk, and exerpeudic stationary bike. I also got Camtasia studio and a few other little softwares.
As far a mobile stuff, I got:
Samsung Gear Sport Watch
some peripherals, like cases etc.
As far as your chromebook goes, @nigelhealy , I bought a Asus Flip C302 last year and I LOVE it.
I was able to find the one with the M5 for under $500 last black Friday (2017 - I think I paid $425 or so). I love the USB C charging, the touch, the flippiness, the SD card reader, and the speed. It's not overly resourced (4GB ram) but that's more than enough for a chromebook. Any heavier lifting and I wait until I'm in the office. Some products I bought / won this year that I can't live without with this chromebook:
Anker Powercore Speed PD. This battery can seriously charge my chromebook while I use it. It's changed my life. I don't even worry about sitting near an outlet anymore at all-day work meetings or design sprints. That battery has more than enough to keep me going until I sleep. Even when we pull 14 hour days. It also comes with a PD wall plug and a USB-C to USB-C cord. Amazing deal.
Anker usb-c to hdmi adapter - there are several versions of this but the simpler the better in my opinion. I'm sure all of the little bells and whistles (ethernet ports, usb ports, etc) are cool but I like this one ALOT. https://www.amazon.com/Anker-Aluminum-Portable-Supports-Chromebook/dp/B01MYUCWOK/ref=sr_1_4?s=electronics&ie=UTF8&qid=1546922424&sr=1-4&keywords=anker+usb+c+hdmi
Anker usb c to usb a adapter - for when you need to plug into the past. solid, ,small, lightweight, stylish: https://www.amazon.com/Anker-Adapter-Transfer-Compatible-MacBook/dp/B078NKPGW9/ref=sr_1_9?s=electronics&ie=UTF8&qid=1546922454&sr=1-9&keywords=anker+usb+c+usb+adapter
As far as 2019, I'm not that excited about anything in particular. I need a better camera for the office for videoconferences, so I'll probably grab one of those. 1080P USB job, probably the monoprice standby: https://www.monoprice.com/product?p_id=35520

Anker powercore fusion
