Every Amiga model should have had a built in RTC as standard, and a hard disk too. It would have made it the definitive business/office computer. Should have been marketed as such and bundled with appropriate software all as standard.
This would have also meant that more games would have been system friendly, with hard disk install options.
As for the old 1.3 colour scheme...I quite like it. Doesn't look like a toy to me.
