Vista Tutorial - Quest PMC

Hey,

I am looking for a new laptop computer. I want to use it for recording TV
shows (just for own use), so I thought a media centre laptop would fit me.

But I don't know anything about media centre (laptop) computers and too
often the shops don't either.

Could you give me some advice on buying a Windows Vista media centre laptop?
For example, what are the more specialized brands on this field?
Do all media centre laptops have a co-axial connection for TV reception?
Is it right that new mobile phones can remotely control the media player of
a media centre laptop through Bluetooth?
What are the things to pay attention to on buying a Vista media centre laptop?
And what model would you recommend?

Thanks you!

Grt,
Wing
