Hello, is not first time writing you I have a new MAC BOOK PRO with 16GB and 256 HD almost all free (i use only office, evernote and few other apps - no games - no image editing) The system is incredible slow, chrome more than any other applications. I can see what i am typing with almost 1 second of delay Sometimes windows stop to work On top of this the battery does not support me more than 3 hors (in stead the 10 it should)
