Please forgive my ignorance if I have missed anything but:

- does anyone actually install from a CD these days?
- Can an ISO be bigger than a CD then be installed on a memory stick?

It strikes me that this is like King Canute holding back the tide. 
Package size growth is pretty inevitable, and even if work now can bring 
the size down to that of a CD, the same problem will occur in the not 
too distant future.

Is it really a problem? Please educate me! :)
