Anyone out there editing HDV on a Sony VAIO VGN-AR11S?

I was thinking of buying a VAIO VGN-AR11S as with the ram upgrade I have been told that it will allow me to edit hdv, burn to blue-ray and watch that on an external plasma,lcd or projector - so finally watch one of my productions in HD! Not bad for an editing system under £2K

Anyone else done this or have any pros and cons on editing like this??
