I have to say that the Mac mini looks nice. I even called it iMac mini before it was released I should say that I was in the same boat in that regard.
Mac mini pro:
1. Style, Form, Size, Ease of Use.
2. Price.
Mac mini con:
1. External PSU brick.
2. Wires.
3. No AirPort Extreme Card.
4. No SuperDrive.
5. 1Gig Ram Limit and Apple Tech only installable.
The iBook and the Mac mini have a lot in common, however when comparing price and features I will say the iBook 12" is a way better deal you get:
1. LCD screen.
2. Microphone.
3. Speakers(even though they are not great).
4. a Keyboard (even though some people complain).
5. a Track pad.
6. AirPort Extreme Card included.
7. More Ram 1280MB
8. Mobility.
This is not brain science the iBook is a way better deal than the Mac mini. For switcher that this machine its targeted its great I guess.
The good news is that the Video Card even with 32MB of ram can drive a 20 and 23 Cinema Display that is great. This system most likely will only handle one display nothing more, though I could be wrong in this regard.
Don't know why they didn't incorporate the PSU into the case. All this seems is like a Cube 2.
This is good news for the G4 chip, which means that it has a lot of life ahead of it.
The PowerBooks really look like the worst deal at present with the introduction of the Mac mini.
