well, our systems are different, my upgrade is MUCH different than yours, all you need to do is buy a 2gb chip ($40).....with me I need to replace the daughter board which also has the processor on it ($160)....originally the 1010's really couldnt be upgraded because Dell soldered the RAM on the daughter board and wanted $554 for the board, I have found the board I need for $160 and will be upgrading soon, there are VERY few with a 1010 and 2GB RAM and I will be one of them, the 2gb for you will allow faster multi-tasking and might help with video playback also...generally it will not be a night/day difference but under some conditions you will see a difference in speed..with me I am just looking for some games I play to be a little less sluggish and probably will also help with the general overall speed of the system when it comes to multi-tasking, it will allow the system to load more things into RAM at the same time...rather than having to go out the the hard drive all the time go grab more data to fully load a program/game or whatever
