Still ipad mini r feels lighter and also mine is LTE so able to use data.
Also, the screen is brighter for iPad outdoors.
Yes yes, even though I have an iPad Air and now the MiPad, I'm still considering getting this year's iPad Mini. Reason being, I'm switching to an 8 inch tablet for outside use. iPad Air is a little too big to carry around, I'm going to leave it for use at home. The MiPad is perfect for this, however, it doesn't support LTE and my 5gb/month data plan

So I still have to bring my iPad Air out
I think iPad Mini still has a couple of advantages over the MiPad
1. LTE
2. Better build quality and design
3. Apple's ecosystem (App Store, iTunes)
4. Much much better ecosystem of accessories available
MiPad's advantages over iPad Mini
1. Much more storage and flexibility when it comes to storage. With 64gb model, you can expand it by up to another 128gb with a microsd card.
2. Much much cheaper than iPad Mini. Even if you get the 64gb model and a 128gb microsd card(which is not cheap), the total cost will still cost less than an iPad Mini Wifi-only 128gb
