Convertible is the way to go.
mscion and sulu are on the right path there.
Graphic art is my schtick...so the right tools for the job eh?
When you need needle point precision ...
when you need penabled work done that requires finesse...
when you want to be sloppy and simply use your fingers for casual navigation and use....
when you need a tablet and then need a laptop keyboard a moment later...
well then the convertible tablet laptops I mention below are the best for the job.
I have a couple of lenovo's
and 3 toshiba portege's the last model m780 is thick since it has the optical cd/dvd bay...but it is more than worth it. On one of my m780's I have it's ram maxed out.. and a 1 tb hard drive in it with no os installed it is purely for storage. I popped the removable optical drive out and bought a $10.00 optical drive-bay secondary hard drive caddy. I carry 4 laptop hard drives with me which have on #1- win7, on #2- 4 of my art distros, on #3- about a dozen distros for work and play... , and lastly on # 4- I have distros for experimentation , libre distros , rr's (rolling releases) obscure releases and the like etc. They all share the common internal 1 tb storage so I don't have to shuffle data around or have duplicates wasting space on every distro.

I have found in my travels that the toshiba portage line ...esp. the m700, m750 and m780 are fabulous...complete... no dock necessary . a step apart from the lenovo's and ibms. (which aren't too bad either) ...and both the lenovo "x---" convertible line and toshiba portege line work verrry well with linux. Very few distros will not work on the portege line.

I remem. having the serious tablets from back in the day. Fujitsu and the m1400 ....they are great...and all...terrible for when you need a keyboard though...unless you use a portable keyboard...then it's just irritating having peripherals every where hooked up...convertible tablet is best of all worlds...

I don't like the new ones out..."yoga" and crap...sure they are new and fast and thin...compat with distros is either terrible or questionable..I think the direction that most manufacturers are going (other than the portege line and the lenovo "x---" line) is pure garbage.
This is my opinion on what I have found trying out various models pertinent to my graphic work. As well as having a decent workhorse computer that had the guts and ability to do moderate to serious heavy work and play. For real intensive editing and the like I transfer my work for finishing to my relatively new workhorse home computer a w530 (My Desktop Replacement Killer...muahahahaha) it kicks arse.

portege m780 or lenovo x230 is the only serious way to go...
lenovo x230 is 2 yrs old now and the latest x240 is last years model ....and the x250 is due I'm sure.
portege is a few years older 2010-ish ..but frankly the specs hold up in compare.

You can find a portege m780 i5 for under $300...usually around the $200-250 range
a portege m780 i7 for $400-500 usually
And the lenovo x200 from 2010 is still viable as a current model ...a good beast ...and you can sometimes get them for under $100 ...usual price tends up to $150
the lenovo x220 is a little pricey
and the lenovo x230 has dropped from over a grand down into the (if you are lucky) 3-4 hundred dollar range but tends right now 'tween the $500 and $800 dollar range.

Orrrr...
You could say screw gettin a comp of any kind...tablet or otherwise...
you could simply wait until implants are mandatory
