Agree with all of Elkhart's questions, and what I recommend people ask before buying something.
Mixy -- I recently bought the Lenovo X1 Yoga (8th gen i5, 8 gigs RAM, 256 SSD). I freakin' love it. Nothing in Vet school seems to require more than that/the Vet IT department also confirmed that, and I don't actively use any single processor heavy application (hence i5 and not the i7), and I don't crazy multitask between applications (8 gigs RAM can handle 15-20 browser tabs open no problem, while listening to music, and projecting to an external screen -- I'm not video editing, while listening to music, and in the background running lines of code etc, and using excel to run a bank).
The X1 yoga(business line from Lenovo) has the "wave keyboard" functionality -- all the keys recess into the body when I flip the screen 360 and hold the device like a tablet and I really like it. It feels stable and I'm not worried about the keys popping off (they won't, but I still worry), like the Yoga 920 (consumer line) which has a nicer screen and speakers and metallic body, but doesn't have the wave keyboard functionality. Like Elkhart said though, windows 10 diasbles key/trackpad input when in tablet mode. Also, the X1 has a pen in the computer itself which charges while docked (it's on the smaller side and I've read that many people buy another pen from Lenovo that is more beefy (Lenovo Active pen) or a Bamboo (other brand) pen, but it seems fine for me), vs the yoga 920 which you have to keep the pen separately -- similar to the surface pro. If you don't need the 360 ability, there is also the X1 carbon which shaves of a half pound bringing the weight down to 2.5lbs -- you can get that in a regular old laptop version or laptop with touch screen capability (just no 360). So it all depends on what you want/need/would like.
I was previously a mac person but since I can't use the ipad pro with my school's exam software, I had to go windows because I absolutely wanted touch screen with pen capabilities, and the 360 tablet mode was optional. I settled on the X1 Yoga vs the Yoga 920 because of the wave keyboard and internal pen -- also, I really like the classic matte black finish of the entire X1 Thinkpad line. I picked the X1 Yoga over the surface pro, because Lenovo puts their Thinkpad line through a bunch of Mil-SPEC tests (tests durability, ruggedness, reliability -- splashing water, temp extremes, drops etc), and I wanted something I could spray down and wipe off with isopropyl (it's in the manual for the computer, I'm not making this up) after anatomy lab or Z licking it. The surface pro has better battery life, and is lighter -- for sure, but I'm worried about messing up that alcantra fabric keyboard and breaking the pen if it's free floating. Also, using a surface pro that a family member has, I've found that it's hard to use while on the couch/bed as the stand is more conducive to table sitting. I also like having a keyboard with keys that have a little bit more travel in them so I feel like I'm "pressing" the buttons -- the list goes on, but you get it -- it's all personal preference items from here on out. Good luck! Let me know what you end up getting!
Aw yeah! Another vote for Lenovo -- love it!
