This is great.. your dad is a survivor.... one of our other members on RDOC (Sharifah) used to write about her laptop & i would exchange emails with her while she was in the hospital. i've only used a big box computer since the early 80s. however, i ran out and bought a 10 inch laptop before my surgery and used it extensively in the hospital when i couldn't talk. i used it to communicate with my doctors, nurses, wife at my bedside. i also stayed in touch with friends and news over the internet. the hospital was wired.
so i would highly recommend you get your dad on a laptop for ease of communication until they get something else for him.
