I have used 3 B&S engine on lawn mowers. Does the job ok. never got excited about them. Black block that makes some noise and reliable. Not impressed with its power but it was robust for the application. I particularly don't like the 190cc side valve engine. Ho hum performance, difficult to restart when hot.
The new 2100 series engine looks very nice with modern specs. 420cc is a lot of displacement, useful for 32" and wider snowblower. I wonder how's the fuel consumption for something that big. Hopefully we see more of this engine in snowblowers. But if everyone is shopping to a price point, I don't see this premium engine being put on a snowblower. A shiny new engine that is non Briggs is cheaper, and they will be a more attractive buy if there are no issues.
I bought the Blue Ray and PS3 devices for their wireless capability to communicate with the laptops primarily because I use my computers as my media source. Such as videos and pictures we take on trips etc. I'm not much into movies but my wife is. She usually downloads them or buys pay to view from our satellite service provider.
I got the Apple TV and the iMac for wireless digital slide show and music. I can queue up a show very quickly on the flat screen TV. I love it, I can do the Ken Burns slide show effects with music. It sure beats the the olden days of using Kodak carousel slide tray, projector, retractable white screen, and darkened room.
