It's just the natural evolution of a GPU to eventually be converted for notebook use, and now we see early evidence that Nvidia will be making a mobile version of Fermi ready for sometime next month.
A listing on Eurocom's site for configuration of one of its laptops lists a 2GB DDR5 GTX 480M Nvidia DX11 100W part as a $380 upgrade option. Since then, the option has been removed from the site, likely due to the fact that it's an unannounced product.
Of course, an Nvidia partner listing a product prematurely is no means a confirmation for the product – but this does offer some hope for those waiting for a new-generation Nvidia part for any upcoming notebook purchases.
Battery life with Fermi in a laptop: less than windows boot time.
Why buy a desktop PC in a laptop form factor?
Or can it?
High end laptops with the mobility 5870 run luckwarm, reaching temps slightly above human heat (notebookreview displays it pretty clearly in many product reviews).
But Fermi runs at almost the boiling point of water. Assuming that the cards are half as hot, it would still be around 50 degrees at your fingertips. Not to mention the fact that it can harm the other parts of the machine because of the lack of real estate for airflow!
