OMG i have buy the wrong ipad!

Ya ya . I think it was a mistake buying this ipad .. Wanna know why.. I bought a 16gb ipad.. And the more i used it i know now its not much of a space .. I should has buy 64gb. I found my self exploring apple store n buying apps. And all the apps was great.. I keep wanting to install more n more.. Now im starting to see my space is getting low. Since i havent add music or video in it yet that mean soon ill bee running out of space. Now i know why apple is so popular among my friends. A while back when i was using samsung tab i always have a speceto spare in the sd card so i didnt notice any issue about storage. Thats why i think 16gb is enough for my new ipad. Now ... Arg so damn wrong. What shall i do? Buy a new 64gb ipad??
