This is what I do too. I stayed on PS2 for a while, despite always having a PC that could support the game, simply because I saw no good reason to go through the download and install process when PS2 was working fine. I finally switched when PS2 would freeze at every ToAU cut scene.
I don't give a flying fig one way or the other if PS2 support continues, but I can honestly say for the record that I don't miss anything about playing on PS2. I have the comfort of console in my recliner and a USB controller and an HDMI hookup to the TV. The game updates faster on PC, I never freeze on NPCs, it looks better, and man do I love being able to turn off weather effects. If I want to watch TV while playing I just unplug the HDMI, switch inputs on the TV and watch the game on a decent monitor.
