I don't think these are unreasonable for a 2017 device right?
1. Ram:- More ram. It would make it easier to have many application open at once and multitasking would become significantly more efficient. One gigabyte of ram seems reasonable.
2. Multitasking: Downloading while playing a game seems reasonable. Not having to suspend one software to open another also seems cool.
3. Resolution: This is one of the most important spec to improve. 240p is horrid. I am expecting at least QHD display in the next gen.
That is really all for now. I have to play more with the 2DS to see what needs to be improve.
