Well, you guys were right. I should have listened. After getting the 16gb today from FedEx, synched apps I already owned. Available storage immediately dropped from 13.8gb to 10gb. Local Apple store had what I wanted in stock - 64gb wifi white. I can only imagine how new, upcoming apps are going to additionally crunch space. Breathing sigh of relief and happy Apple provides their generous no questions asked 14 day return privilege. Now future proofed.
