I purchased the ipad 4 64gb model + LTE from macmall for $489 a few weeks ago. I have someone at work that offered me $550 cash today for the ipad. I saw that bestbuy has the Retina Minis for $349.99 this week for the 16 gb (tho I may opt for the 32GB for $449.99 due to the size of apps today). I refuse to get the air because Ive seen how fragile they are first-hand. We dont need to debate this here. I am concerned about the dust under the screen issue and the image retention problems Ive heard about recently. Should I sell the ipad 4 and pick up the ipad retina mini? I will be losing significant storage and the LTE factor. Thoughts? Thanks in advance for your opinions.
