I got my first flat 27" Toshiba. It's good, but there are a few things I think it does somewhat poorly compared to my Trinitrons.

Things it does better:
>actual good convergence throughout the entire screen
>consistent focus throughout the entire screen
>better purity
>much better and cleaner composite output
>more natural colors

Things the Trinitrons do better:
>vastly superior contrast and black levels
>vastly superior white balance
>much better audio
>slightly better and more consistent geometry (the Toshiba shrinks a little on the right side)
>center of the screen looks sharper (it loses a bit of focus on the edges)
>way less blooming

I'm a bit conflicted on which one to use. I think I like the colors on the Trinitron better, despite the Toshiba looking more accurate. The better white balance and black levels gives the picture much more depth, it really shows on games like Silent Hill 2. I think the tube on the Toshiba has less hours though.
