Like most others, I see AROS as the future Amiga. The things that I think would give it the biggest interst boom would be:
1) Define a reference platform. For example a Via board. I'm not saying there shouldn't be drivers for other hadware, but it would help to be able to say X hardware will run AROS.
2) E-UAE. The better it is and the more integrated it is the better. Perhaps a E-UAE package system, so you just add your ADF to the pre built package and away you go.
3) Office suite. Actually just a word processor and spread sheet.
4) Web Browser (e.g. Firefox)
5) A TV mode. What I mean by this is have IR software, and allow the system to be booted in such a way that you can boot directly to a gamepad/Remote controlled UI. This is sort of done with MythTV, but since Linux is where it is, MythTV and the remote control software is a patch at this point.
I know that AROS is unlikely to ever have the kinds of games that XBox or Playstation have, but there are a lot of people that would love to be able to turn on their system, use their controller to pick a game, and sit and play a 2D puzzle, platform or shooter on their TV.
The one niche that has not been filled is what the old C-64 had. A programmable game system.
