I have a PS3 and an A2 as well as Panasonic, Pioneer, Yamaha, Crestron, and other gear. I buy what works and make sense. I evaluate the products available to me and try not to make stupid rush decisions on my purchases.
In the case of Blu-ray, I purchased a PS3 on opening week as a preorder and made one of the best decisions possible to this point with the format. Strange, but just spending $129 on my A2 and I feel more robbed than I did with my $600 PS3... I don't think I'm alone on that.
Yet, when I get a stand alone player for my home, I'm likely going to be leaning towards Panny or Denon in about a year - probably not Sony since their handling of regular DVD material, which I have a great deal of, is typically rather poor.
