Are there any good Windows 10 tablets to replace an old Surface RT?

John's wife wants to replace her Microsoft Surface RT, which she uses in her job as a tutor. Are there any affordable Intel-based tablets up to the job?

My wife has used a Microsoft Surface RT tablet for a few years in her job as a tutor. She has found its size and the touch keyboard invaluable in her planning and writing up of lessons, especially as this often happens in the car between pupils. Unfortunately, it is becoming less reliable, and much slower, and she is looking for a replacement. She has looked at the new Surface Pros, but does not want to spend more than 500. She requires Microsoft Office, a long battery life and portability.

By the way, I also wanted to thank you for the advice you gave my daughter in What sort of tablet should I buy for drawing? Niamh bought a Wacom tablet and is very pleased. John

Microsoft launched the Surface RT in 2012 when the tablet market looked promising. It was the first tablet to run Windows on an ARM chip, which provided long battery life. It also made it incompatible with all the traditional software written for Intel x86 versions of Windows, including viruses.
