I have an iPad mini 3. I'm thinking about upgrading to the mini 4. I can get £200 for my mini 3 of I sell it. The therefore I'd have to pay £279 to upgrade to the mini 4. My question is it it worth it? Yes I know about all the specs on paper Improved colour gamut, laminated display A8 processor 2GB of ram 8 mega pixel camera Split screen multi tasking I already have an iPad Air 2 which is my main iPad. I use the mini 3 for watching videos on my daily commute. I don't use it at home so I'm wondering if it's worth upgrading it. However on the other hand I'm noticing that my mini 3 is feeling a little sluggish.
