Andre,
making the commitment to the whole vinyl thing is a big deal, and i respect your various rationalizations as to why it's not for you. if a friend asked me whether it's worth it compared to digital....we would end up having a long conversation with me asking many questions before i would answer him/her.
all that said; your point about.....
......is simply wrong. sure, in a theoretical sense Lp surfaces deterioriate. but in practice this turns out to not be an issue. i have many Lps where i've played them literally thousands of times......without a difference. it does require respect for keeping things clean and such.....having good equipment properly set-up....and all that. might hundreds or thousands of plays add a 'tick' or two? maybe. but if a tick or two screwed your head up, then vinyl is not for you anyway.
i don't have one Lp which i've switched out of my use due to wear. i've bought back up copies of many Lps mostly in case one gets scratched, or anticipating increased value, not wear. and i've yet to break the seal on any of them. playing an Lp on a damaged or mis-aligned cartridge can hurt them and i do 'occasionally' find used Lps like that.
in fact, compared to the supposed 'perfect sound forever' CD's, Lps are indestructable. i'll agree that digital files have advantages in storage and should not be vulnerable to the ravenges of time, but like MEP infers, so what?
ease of use is one big reason i listen to digital, along with access to music i don't have on analog. and those are very important issues. and i agree digital can sound very very good.
