well, took a better look today
between the pw7 and the hitachi 7800, both plasma, both 42"
you see more 'noise' on the 7800, i would attribute this to higher resolution actually making things more detailed, but the overall result was that it's noisier.
the pw7 looked the way it did, still good.
i also took a look at the 50 inch toshiba, 50xp47. not bad really, only bad thing about it is the external tuner, aside from being an older model (i presume). upcoming toshiba's are 55 series, with 48 as the one's that are currently in the market. don't take my word for this, i'm only guessing.
lastly, comparing plasmas to lcds, it seems that as far as detail goes, lcd wins. lcd wins in terms of brightness as well. but when it comes to big areas of non-detail, you see all sorts of banding effects, which only disappear when you're viewing the screen from afar. still, the 37" tosh lcd is priced the same as the 50" tosh plasma
oh, one more thing, i finally managed to view dlp rptvs right. the tosh 62" dlp looked grrreeat, but only at 10-15' away. otherwise, it sucks.
