Over the past couple of years, I've noticed that the "Cyber Monday" deals have really gone downhill. It seems like online retailers actually have been focusing on Black Friday to pull people away from the actual stores. Some online retailers like Amazon.com and Buy.com match almost every single doorbuster deal for all the big-box retailers and have it available HOURS before the stores open, with larger quantities in stock. Keep tabs on that website I linked before, and get online at around 10PM ET on thanksgiving to start watching for the deals to pop up online. Depending on the "location" of the online stores, they will a lot of times put up their deals at midnight their time.
However, it's my personal opinion that you won't see any "good" good laptop deals this year, because everybody is going to be focusing on tablets/e-readers/ and honestly game bundles (due to the MASS amount of holiday games this season)
