Easy Upgrade
My wife is not a power user. For years she could check email (using the icon with the label "Email"). If she wanted to create a document in Word, the kids would help.
But she's getting better. She can create her own Word documents, print them, even find things via Google.
Since she's not much of a power user, her last upgrade was to a single core Pentium desktop with 1GB RAM and a CRT monitor, running Windows XP. It was never a fast computer, but it kept up with her needs.
