Thanks again guys for all the feedback and Excellent link Shaun,very helpful.
I am now torn between a number of laptops I am looking at, one of them being the LG E-500 that Vash has and another Toshiba satellite model with a few extras but it has Vista home premium.
So now I have another question.
Does anyone know if programs like Registax, Deep sky stacker and Photoshop run O.K with Vista? And if so with Vista being a bit of a hog and whilst running these programs will it slow things down considerably?
Cheers Daniel.
