Almost the the same for me. I had a C64 and you could switch it off and immediately on again. There was no boot time but if you did it too quickly it sometimes behaved strangely. That was because there were bits and pieces of the previous RAM contents still there. The most obvious effect was remnants of the old application on the screen. So no boot time but still had to wait 3 seconds. When I got my 386DX(ha!) I thought the boot process was so much of a hassle that I seriously believed it would just be a matter of months until that problem got fixed and newer computers would be instant on again. Oh boy was I wrong.
