Dunno about emulation.

There is nothing at all cheap-feeling about the iBook; I can type at very high speed on the keyboard, which has a very pleasant feel (as laptop keyboards go). The screen is nice, bright and has good contrast and viewing angle.

One thing I should point out is that you probably want to adjust the colour profile. The default sRGB one is quite horrible. Take 10 minutes to calibrate it properly. You'll thank me.

Also note that you can alter the contrast with CTRL-OPTION-COMMAND , and . (that's comma and full stop). You want to do this, because you can only alter brightness from System Preferences.
