Amiga OS 4.0 on Laptop

[danwood]

If you want "Amiga NG" with Laptop support, your best option is MorphOS on a Mac PowerBook (PPC).

Or AROS of course which should run on most bog-standard PCs including the laptop the OP probably already has.

If you just want to run classic Amiga apps, you can run up to AmigaOS 3.9 on WinUAE, the best way to get it (and all the roms legally and easy to use) is to buy Amiga Forever:

I've been itching to reg MOS on my PB, as I do really enjoy the OS and heartily recommend it to anyone who will listen - is inbuilt wifi supported?
