since i'm not a tech blogger, I'm confident Windows 7.0 news will not drive any traffic to my blog! I can see several application uses for the multitouch screen, but I agree it won't do much for sales for a long while and besides Apple will probably launch an iMac with it before Win 7 launches.
I'm sure it's way too much to hope that the secret Apple device you cite is an updated AppleTV with true HD and DVR and slingbox functionality built-in allowing me to beam all of my media to any video display I have access to or my iPhone...but I will hope anyway!
