We uncomplainingly paid those prices for new "technology," not to acquire a hard copy of the OS we'd already paid for when we bought our Macs.
Doing the math: 29 + 69 = 100 roughly. Therefore, we now pay 30 dollars (or 23%)less, even if we opt for the [reusable] thumb drive.
Seems like we probably ought to press on, uncomplainingly.
[i do see your point about 'new tech' wrt OS upgrades of an old machine, versus the need to emergency boot a new machine. iduno, when i get Lion i'll look into it a little deeper i suppose.]
