@david k I'd look into a chromebook very seriously.
If you need to interface with work based systems things might be a bit involved/tricky but for everything you are likely to need domestically I think they are fine.
Far cheaper, far more reliably, massively better battery life (up to ten hours) than a PC.
You don't need anti virus and you escape the sheer nail-biting horror of windows updates - updates take place seamlessly and quietly.
Some folk think that you always have to be online - not true.
I have two chromebooks - a nice metal cased 14 inch one that cost me about £170 and a smaller 11inch one for various things including cycle touring - that cost £99 in a sale.
I create all my cycling routes for the garmin on the chromebooks and can do the final text editing stage totally offline.
If you go down the chromebook route I'd look at one that is ready to run android apps as that potentially gives you a bit more functionality. Though be sparing about which android apps you install.
Neither of mine were android ready when I got them - the 14inch updated itself to run them a fair while back - the 11 inch is on the wait list for this update and it is supposed to happen, but I am still waiting.
Final advantage of chromebooks is that if you have two on the same account they automatically sync with each other and backup to the cloud is automatic - handy for careless souls like me. If you have an android tab on the same google account, they will also sync with that automatically.
The one down side is that google knows more about you than you know about yourself - dread to think what they think of me.
