When I upgraded to X3 this spring with a new computer, I left all my old 3rd party plugins behind...which I had folders full of...and kept all the installs, etc. Now, I only use what came with Cakewalk...and the Sony stuff I got with CD arch/Sound Forge/vegas/Acid. The Sony stuff I basically only use in the Sony programs..if I use them at all. My machine is so unclutter now in that dept, it is actually great. I don't need *legacy* plugins, because all my old stuff is already mixed and the few sessions I've revisited, my preference was the newer 64 bit plugs anyway.
It's like the old days in the studio when I had one Eventide, one LA3A, natural reverb chamber and a handful of good mics. You made decisions and moved on.
Not to mention, I LOVE reading about the new stuff, but the GAS is now gone. I'd rather have something more useful than another virtual reverb or compressor. That *something* might be..... another guitar!! ;-D
