Well, I am sorry to hear that you aren't happy with the Apple products you have used. From my years of experience in the computer industry (9 years with two of the largest resellers to corporate and government sector) with product training in a vast list of major mfg of software and hardware companies, I can say that I wouldn't touch any other company's product that makes a hardware alternative. WHY? Less problems overall, better customer satisfaction. yeah, not everything is perfect and Apple could improve their iTunes software. I agree that they should support more file formats like FLAC and possibly others, but there is usually a work around for most issues.
Artwork, I usually only have problems with artwork on albums that aren't sold through the large distribution companies and I have to find them elsewhere and I wish that it would keep the artwork I paste into the track, but unfortunatley it doen't.
Now, Apple has a site that anyone can go to in order to give feedback, suggestions, etc. and many times they do actually come out with fixes, or new products to address my feedback, so it might be worthwhile speaking directly with the company rather than airing your frustration on a Meridian forum (just a suggestion). But then again, there are plenty of Mac fans that might be able to help out.
Here is a link to Apple's feedback site. See if other companies have this, most don't.

Apple users don't have these types of problems and thank Mr. Jobs and company for an alterenative where the software and hardware is designed and supported by the same company.
Just my 2 cents.
BTW, I don't work for Apple, but I have been involved with selling their products, along with other major mfg. and I personally have had much better success in dealing with problems using Apple than Windows based products.
