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.

Yes, if you want touch screen. They have a specially designed screen for that.

well right NOW windows 7 does support touch, but NOT multi-touch, they are saying it will when the final version is out
