Maybe Alexa couldn't handle this query for you:
In regards to your ddr3 and 16 gb ram snark: see this thread
https://www.quora.com/Why-is-Apple-still-using-LP-DDR3-in-their-MacBooks-instead-of-LP-DDR4
"Intel, which is at this point the only CPU manufacturer making CPU’s apple can use, only supports the following RAM standards on their laptop CPU’s:
DDR4-2400, LPDDR3-2133, DDR3L-1600
DDR4 is not available in a low-voltage (DDR4L) yet, normal DDR4 is bigger and uses more power, and DDR3L uses a lot more power and is slower than LPDDR3. Meaning LPDDR3 was pretty much the only option left. Also, running at 2133MHz with lower CAS latencies, the RAM in the current macbook pro’s scores on par if not better than budget DDR4 in most laptops.
Apple could have gone for DDR4–2400, but that generally uses 1.4V instead of ~1.2V,meaning the RAM uses close to 20% more power, takes more area on the logic board (meaning a thicker laptop or smaller battery) and the CAS latencies are usually worse on DDR4, meaning actual gains are minimal at best. The only real drawback of using LPDDR3 is the limitation of 16GB, which again is an intel issue."
If you search (don't know if Alexa can help), Dells low travel keyboard is also having issues similar to Apple's (ifixit forums). also, looking at benchmarks (Geekbench, those guys seem to know what they are doing), Apple computers do seem to be in the high range of the configured specs.
If your complaint is more you don't want thin, don't buy thin, Thin will have the same issues (soldered low voltage ram, thin keyboards, tight thermal tolerances) whether from Dell or apple or whomever. You know no one can change physics right?
