Rumor has it that Tony Duell may have mentioned these words:

That was my thought, too. I've seen good sets that have TX6, 7, 8, 9, 10, 
15 and up, and I think there's such a thing as a TX12, tho I've never seen 
one in captivity. ;-)

I've seen modern hard drives use both TX6 and 8.

Also, if one has a very good set of both SAE and Metric (hex|Allen) keys, 
you can often find a key that will fit the center of TX10 & 15 screws well 
enough to install/remove them in a pinch; I don't recommend making a habit 
of it (read: don't think you're covered toolwise without a good Torx set 
nowadays) but if you have no other choice, it can be made to work. It's 
like I always say: If it's stupid but works, it ain't stupid. ;-)
