All of these have been long-requested!
AMD mobile APUs are hopefully coming in the future thanks to their popular demand.
Ethernet Expansion Cards are the most popular card request and I believe that they are being designed and (hopefully soon) produced for consumers.
Touchscreen options have also been very highly requested, and is possible as a replacement for the current screen for those who want to upgrade, when that eventually arrives to the marketplace.
As for a 64gb storage card, I haven’t seen many requests for something that small but it could be something that exists in the future if enough people get behind it.
