For me it's not nostalgia. Nostalgia made me build my Ravnica Block Cube, which is what I experienced when I started playing. I just like many aspects (not all though) of old school magic and I adore the old card frames (even though it took me over two years of playing to see an old frame card).
I think I also like the lower power level of premodern, especially when it comes to threats. It certainly is closest in playstyle to my main cube, even though that has tons of cards printed after 2003.
