Tim has issues with one application, but blames the entire operating system. Is this fair? Further, the trash bin problem of not having an "Ignore All" button has always been around. That does not mean the operating system is becoming worse, just that an age old frustration (albeit a very obscure one) is still around.
I have some issues with Lion, but they are grounded primarily in my complete satisfaction with Snow Leopard and lack of desire to change (if it ain't broke, don't fix it).
When Tim says "there were many things worse in Snow Leopard than in Leopard," I cannot recall a single one. In fact, the Snow Leopard release was undoubtedly a very well received one.
