performance in everything else besides graphics will be decreased, because you have will have less RAM dedicated to regular everyday application usage. I think that you should try it and see what you think. See if the graphics performance gain is worth the performance loss of everything else. You will like the 256 mb shared memory a lot if what you want to do is play games, which a netbook isn't suitable for but still.
But, the performance loss in everyday application usage wouldn't really be as dramatic if you upgraded to 2GB or RAM.
So really, a ram upgrade and uping the shared memory go hand in hand.
And before you upgrade the ram, I am gonna ask if you could give me the exact model number of your friends netbook?
I researched everything with the following term: System Model HP Mini 110-3000
But it appears that that is just the model series. Here are all the possibilities: http://h20180.www2.hp.com/apps/Lookup?h_lang=en&h_cc=us&cc=us&h_page=hpcom&lang=en&h_client=S-A-R163-1&h_pagetype=s-001&h_query=HP+Mini+110-3000+&submit=Go+%BB
Some of the 110-3000 series have upgradeable ram and some do not..
