So, in your view, a graphics card that has 10 MB on it and shares 240 MB of system memory is the same as a 250 MB graphics card? There's a big difference between 250 MB of dedicated memory on a graphics card and a shared memory architecture in terms of speed.
Integrated Graphics Solutions
Integrated graphics solutions, or shared graphics solutions are graphics processors that utilize a portion of a computer's system RAM rather than dedicated graphics memory. Such solutions are typically far less expensive to implement in comparison to dedicated graphics solutions, but at a trade-off of being far less capable and are generally considered unfit to play modern games.
Also from Wikipedia:
The disadvantage of this design is lower performance because system RAM usually runs slower than dedicated graphics RAM, and there is more contention as the memory bus has to be shared with the rest of the system. It may also cause performance issues with the rest of the system if it is not designed with the fact that some RAM will be 'taken away' by graphics in mind.
I agree with you that the NVIDIA option for the M1210 is better than "a plain old 64 MB card," but it's not the same as a 256 MB graphics card. Dedicated graphics RAM is much faster. The point of this whole thread is that many people rightly assumed they were getting the latter when they weren't.
