Hi Chris - sorry for the delay! I had a relative who was in hospice and I've been dealing with that. I will be gone the end of this week for services so I wanted to get this away before I had to leave.
Summarily, and FWIW, I agree with your "260/460 vs. P40" observations - for you that may end up being the better choice. Just know that you are not likely really requiring a workstation class configuration and the DGPU doesn't sound like it will do much more than idle ;-) That said, in the given price range, having a little more capability than you strictly need is not a bad position to be in.
I know this won't likely matter, but recognize that the DGPU is a Quadro card, which is meant for engineering stuff, not game stuff. A Quadro card will give you improved performance over an integrated Intel graphics system in most applications, but a regular consumer GeForce card will routinely outperform the more expensive Quadro card in games. If you don't play demanding games, that won't matter to you. Of course, if you ever start using engineering type apps, you'll be happy you have a Quadro. OK, enough on that, LOL.
As I mentioned, the P40 is a bit "chunky" when compared to the X1 and the Surface Book, but it sounds like you don't place a high priority on the "thin and light" aspects. Coming from an X220T, the weight of a P40 won't seem bad to you and, in fact, may seem lighter due to the larger chassis (psychological effect.) IF you want to go a little more "svelte", the X1 brings that to the table, albeit at a higher price that may not be worth it to you. The SB is my personal "do all" device of choice, but again, your usage is different than mine - I am mainly using it in Laptop mode and only use it in tablet mode for testing purposes whereas you do actual, real world property inspections. I can only imagine that IF I were still actively appraising, I would value the detachable tablet aspect... As for battery life, I am getting around 4 hours of regular use when detached and about 9 hours when attached to the keyboard. I always have a car charger with me in my glove box (old habits die hard) but if I am traveling, I have yet to actually use it - I simply reattach the tablet section to the keyboard section when I get in the car... The 13.5" screen sounds smaller (well, mathematically, it is smaller, LOL) but in real world work usage (vs. watching videos), the 3:2 aspect ratio makes it a much better screen - you can actually see more things that matter due to the aspect ratio. IMHO, all work devices like this should ditch 16:9 screens (YMMV...) Again, this is because all (most?) regular programs have stuff (menus, task bars, etc.) on the top and bottom, so your vertical space is at a premium - and it gets more precious as the screen size decreases! On a huge, high-res desktop, a 16:9 screen is not bad, but on a laptop, it is not a good choice. Your Dell is a 16:10 monitor at 2560 x 1600, and it is a great one. I now use a 16:9 monitor as my main screens, but it is a 40" UHD (3840 x 2160) so the combination of higher resolution and larger size combine to make it an upgrade, but as I go smaller, the aspect ratio makes a big difference in my day-to-day usage. Don't misunderstand - the 14" 16:9 screen on the P40 will be an upgrade to your X220T screen (even if it were actually working, LOL) so I am not advocating that you go with a Surface Book based on that alone. The SB has its detracting items - the screen is glossy, and while it has built-in aspects that minimize the glare, the matte finish on the P40 would likely seem better to you out of the box. For me, even though I much prefer a matte screen, I was able to live with the "raw" screen and eventually put an anti-reflective screen protector on it, largely out of preference (vs. absolute performance.) I have not found a plethora of bump case/straps for the SB tablet (hereinafter "clipboard" as that is the term their marketing people use) but then I've not found any for the P40 or X1 yet, either. When I get back, I will look around some more as others ask me this all the time and very few actually volunteer info when they do find something themselves :-\ FWIW, I have used strips of Velcro to attach a strap to much heaver devices and found it to work just fine, but I completely understand that most of us want a pre-engineered "bump case" type solution that we can find on Amazon with 5 stars and just click on it for 2nd day delivery ;-)
So, all that said, once again there is no "perfect" solution for you - each of the top units involve some sort of compromise. You will need to weigh the pro and con aspects and see which fits YOU the best. I can only help by describing what I have learned through my own experience added to feedback from other appraisers. I wish you could easily go fondle each unit yourself side-by-side, but I recognize that your more remote location doesn't make that easy (understood - I used to live in the sticks, too.) I will say, however, that this selection is obviously a very important decision for you and is something you plan on living with for another 5 years (or more?) so IF any of the items I have highlighters are of concern, it may be worth your time to travel to town again an schedule stops for fondling. In the end, though, each machine we've discussed is a quality piece - I can imagine that they will perform (more than) adequately, and will be a welcome upgrade over your ailing X220T. I'd not spend much more time "agonizing" over smaller details as it seems to me that you really need (vs. just want) something and the longer you delay, the more frustrating it is (loss of productivity?)
[Edit] - Finally, there is the 4G LTE thing. As you know, the SB does not offer built-in 4G LTE but that is offered in certain Lenovo models (some "coming soon"?) so you'll need to really think that through. Also, consider carrier choices IF that is an area of concern. As an example, the HP Spectre X2 is a pretty good device for the buck but the 4G LTE is only through Verizon. The Verizon limitation absolutely kills it for me, but may not be a factor for others - so YMMV on that stuff. Again, I can easily "tether" so "no big deal" there, but that may be different for you and (as I said before) IF I had an option for built-in 4G LTE through AT&T on my Surface devices, I would absolutely get that, even though it doesn't actually make the best economic sense for me - We all have our own individual "hot buttons"... ;-)
Please let me know how I can help. I know I get long-winded and many time my posts sort of "meander"... :-\ So, if you "bullet" some specific questions, it will be easier for me to anser in a more organized (and perhaps slightly more concise? LOL) fashion. I am happy to do so in hopes that it helps you and/or other members here. I'll be around today but likely traveling tomorrow through Saturday.
