Yes you should. Even if they seem like they dont want one or think they are to complicated they could benifit a lot from a little internet. When they have to pay bills instead of them having to run around town they could just pay it online.If you are also worried about them financially online banking will help you keep a record of their bank account and expenses. If you do get them a computer make sure it is a simple user friendly computer because they really will not use it it they do not know how.
