Multi-touch Windows 7 laptop question? -

I currently have Windows Vista Ultimate - Dell Inspiron 1520. Will I be able to just add hardware to my laptop to make my screen multi-touch if I plan to upgrade to Windows 7 when it comes out or do I have to purchase a new laptop if I decide to upgrade? Thanks.

You will need a new laptop, as this upgrade will require a different type of LCD screen amp; interface hardware.
