Thats wrong.
Anyone who thinks they're going to be color calibrating on a TN display is going to in for a rude surprise regardless of whether the screen is matte or glossy. I say go for your preference on the display on the notebook because any serious professional color work should be done on either an external IPS monitor or an NTSC TV(depending on your work). Even then color calibrating for video can only take you so far because the client will likely be watching your content on a completely different screen. For print, you shouldn't be looking at your laptop display either but that's a whole other story.
