In the meaning of windows and beos applications, yes. |
| 11 |
However it is not like ReactOS uses the windows graphic shell. It has |
| 12 |
its own windows-like graphic shell. |

When I talk about "userland", here, I mean more the core stuff, like |
| 15 |
coreutils, graphics and the like. |

Few, indeed, but that's irrelevant in this context. They exist. |

Yes, very probably. However it's a kind of decision I don't really |
| 31 |
understand... using a Linux or BSD as the underlying kernel would give |
| 32 |
you immediately tons of drivers and stuff, even if you want to rewrite |
| 33 |
most of other utilities from scratch. |
| 34 |
Probably I don't get it because I'm not an OS programmer geek. :) |
