I was in a similar boat awhile ago. My responsibilities while traveling include editing two websites, writing long correspondence or editing/amending contracts (long papers were more of an issue in grad school), creating MS Excel spreadsheets, and a little video and photo editing. When writing long papers a good keyboard can save you a LOT of time from correcting mistakes, as well as increased typing speed. A good, integral trackpad also speeds the editing process, and cuts down on clutter from packing an additional mouse (and/or keyboard if it’s a tablet) or if you are working on a small deskspace, or even off of your lap. These are just a couple of the many reasons I opted for a small notebook (my previous travel setup was a 10" tablet, BT keyboard, and BT mouse - I'll also mention that some BT keyboards and mice have BT hiccups in the connection that would not register letters frequently when typing or interfere with the Wi-Fi connection... explanation is complicated).
Do yourself a favor, and go into a store with different tablet and mini-laptop options (like BB) and test out how well you type on the different options, how many mistakes you make, and even from different positions, i.e. typing on the keyboard off to the side like you are transcribing off of other notes/screens. Similarly, try using the touchscreen for placing the cursor in between words (like you are making a correction), selecting phrases, and copy and pasting those phrases into other areas. You might find that it takes longer to do, which might be repeated many times throughout writing an article. The last thing I want to do is make work take that much more time when traveling.
Personally, I went with a now DC'ed Lenovo Yoga 710 11.6" (the 10" keyboards were just too small for prolonged typing for me), and I replaced the 128 GB SSD with a larger 500GB Samsung SSD (I also could have installed a 1TB Samsung SSD but that went over budget; no micro SD slot). It was a BB exclusive version with 8 GB RAM and a 7th gen core i5... and a full size USB port. The USB port also meant that I could charge my phone off of it in a pinch, directly transfer files, or tether my phone when necessary. Additionally, I had a lot of old software on CD and an older portable CD USB drive to install my older versions of Adobe Photoshop, Elements, and MS Office.
