Looks like Dell will be carrying this in the form of a Ultra Sharp model line, namely the U2913WM http://accessories.us.dell.com/sna/productdetail.aspx?c=us&l=en&s=dhs&cs=19&sku=225-4201&dgc=SS&cid=255598&lid=4530577&acd=12309163478274932
Yeah I have an older 32" Plasma that I have to watch out for IR, but its still not to bad but as no pixel shifting so when it needs to be cleaned up its up to me to find content to clean it up, my newer 60" has good pixel shifting and no IR problems at all. And every time I go to a friends house...
Image retention is different then burn-in... though one can proceed the other if done too long. Plasmas have come a long way but its still a good idea to take brakes and play full screen content. The AVS forums will have all you want to know about both problems.
I noticed not one person asked the viewing distance. Given the size and application its very possible that the distance you are watching at may make the fact that its 720p instead of 1080p moot. Go here and get learned up some http://myhometheater.homestead.com/viewingdistancecalculator.html
I can agree that in a purely HTPC case there is no need for lots of 3.5" drives I would say a full size 5.25" serves the practical purpose that there are far more full size drives readily available then slimline. I would love to use the smallest part possible that gets the job done when ever...
