Slower..well..I think that it is just not yet optimized...it is still in beta version so I dont expect performance nor full stability or compatibility. But as for now, well, it is fun to play with and it is even rock stable for now..not one single crash. I surf the internet, email, messenger, copying files over the network I did in order to access the internet and installed some 32 bits apps... Now, I'M looking for 64 bits apps that could be used with.
I setup a dual boot system so I always have my 32 bits windows at hand if I need to do something urgent or critical!
