Pioneer vs. Panasonic plasma

Nano Proprietary won its SED licensing lawsuit against Canon last month. If the two parties can't come to an arrangement out of court this will adversely impact Canon's ability to mass produce SED televisions, because the licensing agreement with Nano doesn't extend to Toshiba, who Canon is relying on for mass production. Given the stakes and the significant investment (estimates range from $1B - 1.7B) Canon has made in this technology, it's hard to believe they won't work out a deal with Nano Proprietary, however this development stands to further delay the release of SED.

The only thing about Plasma - Is burn is NOT a myth.

I watch a lot of 4x3 content (I use black bars on the side, and do not stretch or screw with the aspect ratio) and my 600U has 2 vertical white lines where the 4x3 cuts off when I'm watching widescreen content. It's more image retention than burn in - after a couple of widescreen these dissapate - but plasma burn in is not a myth

goatwuss - what model and how old is it?
many of these issues have been reduced dramatically

in 4th 5th and 6th generation plasmas

So what did you decide on?

I'm taking a look at the 52" Sharp LCD too.
There are some really great deals out there now in plasma TV's that are being replaced - Panasonic, HP.
