Ive been using an iPad mini for years now. I like the form factor and prefer it over a full size tablet. The processing speed and power of the iPad mini 4 is good enough for what I use it for. Compared to the original iPad mini, the mini 4 is a beast.
The battery life is exceptional. I can go a full day on a single charge with heavy use.
I use a life proof case for it, so it's well protected however it is heavier than planned so there is a trade off.
So before I got this iPad mini 4, it was my belief that it was something I just had to have. An upgrade from my iPad mini and surely I would be more productive with this mini tablet in my corner.
I wish I could report that as being true. I haven't been more productive and this iPad mini sits in my computer bag just as much as my other iPad mini did. I don't have buyer's remorse. I just wonder why we always think we need things we really don't.
Kudos to the expert marketing teams out there. It works. I have more things than I need and actually use. 8-)
