Android phones, apps and tablets

I want something like an iPad Air, but cheaper if possible.

Can somebody please recommend a tablet

• does not need to have a huge screen, but resolution should be decent
  
• will mostly be used just for showing photos to people, so good colour / display wanted
  
• does not need to have strong CPU and everlasting battery, would be nice to be able to do a bit of internet surfing and watching some videos occasionally though.
  
  

Thanks!
