My auntie has a fairly old laptop, about 4 or 5 years old, running Windows XP. It does take a long time to boot up. Its had various virus checkers installed over the years and old ones uninstalled, currently running Avast free anti virus.
Over the years Windows slows down, its not just XP, you will find it in Window 7 / Vista. A complete reinstall of Windows and then all the applications will get it faster again, but will be time consuming especially finding all the disks that you put in that safe place.

Often if you ask the person what they use the computer for then you find its not much at all. My Auntie uses the laptop solely to browse the internet or to go on facebook.

So really an internet only laptop would be ideal. Well did you know Google make something called a Chromebook, boots up in seconds, comes with its own antivirus. You can edit Word and Excel type documents and they are stored with google, so if you ever loose your Chromebook you havn't lost your files. It has the Google Chrome internet browser installed for you to browse the web. Its certainly ideal for someone who only browses the internet.
I've not tried one of these in person but more info is here:- Samsung Chromebook for £299 it would be ideal. Its on her list of things to buy.

One of the main problems with laptops/computers is Microsoft Windows itself. Well this dosn't have windows.
