I have also encoded all my mp3s at that bitrate (and CBR). Some people swear by VBR, I don't. Sure the files are a bit smaller but I don't believe they sound any better and the space that is gained with encoding them VBR isn't that much of an issue nowadays, not with HD becoming this big & cheap anyway.
(to be honest : I just don't want to re-rip and encode 5000 songs )

I used 192 because this was the "sweet spot" for me. I don't really hear any difference anymore between 192 or higher bitrates, and it's still acceptable when it comes to the disk space it takes. In some cases 160 is also acceptable, 128 however is NOT.
