If you want a strong hinge, have you considered milspec (military specification) laptops? They have to survive drop tests and the like, so I assume they have stronger hinges.
Lenovo offers several milspec laptops in their Thinkpad line, and they all have Intel dual-band wireless 8265 and an RJ45.
I think the Lenovo X, T, and 13 lines would fit you best. X is thin-and-light, T is more powerful. 13 is, well, 13 inches.https://www3.lenovo.com/us/en/laptops/t ... /thinkpadthttps://www3.lenovo.com/us/en/laptops/t ... /thinkpadxhttps://www3.lenovo.com/us/en/laptops/t ... thinkpad13
The X270 looks to be within your price range. (The other X-laptops look too expensive.) It's an ultralight 12.5". Configured with everything you said, it came out to about $1,200.
Every laptop in the T-line fits your price, but it looks like only the T-470-P and T-470-S offer touch-screens. They're both 14". The P has a quad-core Core HQ processor while the S has a dual-core Core U processor. These also come out to about $1,200.
Finally, the 13, configured to your specs, comes out to only about $900. By default, it has only a Celeron, but you can upgrade to an i5 and it will stay below your budget.
I would note that both the X and the T allow you to upgrade to a huge battery for only a few dollars, while the 13 has no such option.
The T allows you to upgrade to a Geforce 940MX, while the X and 13 are limited to integrated Intel graphics.
I would also note that Lenovo (and many other laptop manufacturers) put a huge markup on their SSDs. So I would recommend you buy the cheapest hard drive and install an SSD yourself. I'm not sure which of their laptops accept M.2 NVMe PCIe and which only accept SATA. So you should check that. You can look at the Lenovo PSREF (Product Specifications Reference) to get more details about any given system: http://psref.lenovo.com/syspool/Sys/i_pdf/psref515.pdf
. If I'm reading it correctly, it looks like the X270, T-470-P, T-470-S, and 13 all have both M.2 PCIe and 2.5" SATA. But double-check. The PSREF also shows every other system characteristic, such as every port (RJ-45, USB, etc.) and every option. So you can see whether the system matches everything you need or not.
