Is a Pentium 4 2.6 GHZ supposed to be faster than a P3 1GHZ? So far, I don't notice that much of a speed difference.... Also, the Wireless keyboard works perfectly, but the Wireless mouse leaves alot to be desired.... It keeps on moving the mouse pointer up to the upper left side of the screen. Anyone else with a Dell Dimension 8300 have this problem? Other than that, so far I'm rather happy with it. It's got to last me the next 5r years before I get another computer ... I'm also wondering what Folders in Windows XP(This is Proffesional Version, on my old computer, I had Home Version) I can delete]. I'm not sure what Dell put on, and what Windows XP had installed and needs to function... Thanks!
