Depends on your definition of better, there is an i3 and e350 version, I took the 350 version, only thing that was better was that it was x64 from he off, and slimmer, but this I think effects build quality, my screen cracked when I was opening it and adjusting the laptop, something I have done on a lot of laptops, didn't think its build would hold up to being thrown in a travel bag, so returned for a refund.
Had a good play with a 350 DM1 thought it was a bit more robust, still not up to my current eeepc 1000H but hopefully it will survive longer in my hands than the 5 hrs of the x121
so have a 450 DM1 at home waiting to be opened.
more interested in undervolting and getting battery life +
