Yes, I know what you are talking about. I'm familiar with the Sony video editing system as I have worked with them in the past.
I have to say that they are very limited in their usability, since they often require specific versions of other software, such as Quicktime, to be installed on your computer to work at all. Sony also does not guarantee future software updates, meaning that if a newer version of Quicktime comes out, and your Sony software doesn't work with it, then you won't be able to do any editing work without the older version of Quicktime present. That's a real PITA when you're surfing online and 1001 web sites complain that the "latest version of Quicktime" needs to be installed...
As for the Viao laptops, they are just too bleeding-edge for me to use as a serious work tool. Sony enjoys using proprietary hardware/software of all kinds - you will notice Viao machines are loaded with unique/specific drivers that come from Sony only, and at times fail to provide/update/correct them. There's a reason why most systems administrators have nightmares when they need to deal with fixing a Sony. And considering how expensive the top-end Viao laptops cost, for the same price or even slightly less, you can buy better performing hardware from other vendors that let you configure your system without all the brand-name garbage thrown in.
That's not to say I don't like Sony - I own a Sony camcorder and digital camera and I love them both, but I won't be buying a Viao PC or using Sony software to author my DVD's.
If companies such as Pinnacle can introduce support for a wide array of consumer HD video hardware in their editing solutions and Roxio provide full blu-ray/hd-dvd burner support, it will give me a better choice and more reason to upgrade from DVD to HD when the time comes.
