Saw the ad for the iPad Air 2 on Staples for $150 off but my location only had the 16GB model in stock. I bit the bullet and love it. Thing I noticed though is I have iCloud Photos on Apple Music on and have 5GB left with all the apps I think I would need. My question is does anyone think with all the cloud services available and I would only be using on Wifi if I would need more. Thoughts? I have a 64GB phone and only use 7.3GB so I am not too concerned especially since it will only used on Wifi.
