4 GB RAM limit

Web browsing takes a lot of memory.  Memory questions are extremely legitimate, and for many of us, 299 or 399 are the same as 199.  I'd happily buy a slightly more expensive version for 16 gb of ram.

I too would have paid more for 8GB, 12GB or 16GBs of memory. But, in the open source ARM 64 world, there are just not that many options. I found that the Kirin970 SoC does support at least 6GB of memory. However, finding details if that SoC supports more memory than 6GBs are not easy to find.

One odd thing I have noted is that ARM 64 Linux distros seem to use less memory than a AMD 64 type. It's possible that the ARM 64 instruction set is simply more compact that AMD 64.
