Must be an age thing mate.
Seriously, though - and all comment on the quality of the choons aside, which will always be a personal preference - while I can absolutely see where you are coming from on this, have you ever wondered if it is because either:
a) we are tied to CDs as being the only "valuable" format because of their very physical nature - you pay for a physical thing therefore it has more instrinsic value than something that comes out of the ether; or
b) you are so used now to getting free *cough* music in this format that it has somehow devalued the concept for you?
And, all joking apart, the age thing is not as daft as it sounds. I resisted buying a CD player for quite some time as, having witnessed the rise and fall of such things as laserdiscs, I figured it was a new geeky bit of tat that would eventually lose its charm and fade away. I eventually (thankfully) bought in to it. Perhaps the whole idea of MP3s as The Medium now just takes a little getting used to?
Food for thought. (Especially with all the Pizza, Eggs and Penne flying around
)
BTW: on a side note, I paid for an extra copy of P4E to send to someone as a christmas present. Was I daft to do that, having already bought it? Maybe. Did it make me feel better having done it that way? Without a doubt. Otherwise my present would have had no value at all to me.
