The ABox is a very nice API to work with and allows a lot
of flexibility. MorphOS is significantly quicker at booting,
loading apps, gui refreshing etc. than most other operating
systems I have used. The ABox already has seen a noticable
improvement in terms of internal modernization and features
available compared with classic Amiga systems.

I think the point to having MorphOS is to have something
different that can provide an attractive, efficient and
blazing fast "single user/home computing" alternative to
Linux, Windows, MacOS etc. and MorphOS is achieving this
already in my opinion. But you can always use both if you
need/want to anyway. :)
