A:AnswerThe Dell comes with Bluetooth, and a 3.5mm port for headphones or speakers.
It has USB ports for a new-style wired Mouse. I do not know what kind of plug is on your old mouse. I personally use a Microsoft 4000 wireless mouse that uses a dongle. It is as good as any wired mouse I have used and it gives me more freedom. I have a Microsoft Bluetooth wireless mouse that sits in a drawer. I avoid it now because it is way too slow and glitches.
A:AnswerMy family has had many Dell laptops over the years (both touch-screen and regular) and have never, ever had a problem with the screens. Treat it right and it will treat you right!
