I vote for a laptop without a floppy drive.
Currently it wont boot on my floppyless laptop
It gets stuck in endless loop seeking the missing
floppy!

I had this problem, though not on my Laptop, I cured it but switching support for a floppy drive on in the BIOS even though no Floppy drive was on the machine... AROS worked fine after that :-)
-Edit- As always, use the latest build of AROS.
