well the ssd didnt work out with this system, even with the updated firmware i kept getting system hangs. crucial took it back no problem.
back to comparing the 1120 to the 1121, i found this http://www.ebay.com/itm/Dell-Inspiron-m101z-Core-i3-Ultraportable-Laptop-Ultrabook-10-2-/300844622828?pt=Laptops_Nov05&hash=item460bbca3ec
and if you look at the windows experience index (i know not the best way to judge performance) the 1121 has a score of 2.3 as seen here
thats with 6gb of ram, my 1120 with 8gb of ram gets a score of 3.7. so i guess the amd version is a little faster, if anyone was wondering. the 1121 i posted above also has an ssd, while mine has the original 7200rpm samsung drive back in it. i am guessing its the amd graphics giving it the better score.
