Actually, this part is also funny, nowadays:
an easier interface to introduce to users either new to computers or used to text-only input...
My two-year-old twin grandkids (okay, 2 years, 7 monhts) already know how to use a mouse, not to mention an iPad, Nook, and what buttons to push to find the Netflix movie they want to watch. (And the granddaughter [there's one of each gender] figured out how to *ORDER* new pay-per-view movies! You can bet the parental control password got added real quick after that episode!)
Don't get me wrong, I was one of those who doubted that people needed anything more powerful than an 8-bit computer. But at least I changed my mind quickly when WYSIWYG word processing appeared.
