Apple iCloud storage plans simply do not make any sense.

Skydrive and Google Drive offer 15 GB of storage space for free. In contrast iCloud just gives 5GB of free and charges users for extra 10 GB!!

Even thr large storage plans of 100 GB are pretty high compared to Google Drive and Skydrive.

What exactly is Apple's iCloud strategy? Yes, Apple products are generally premium products but does it make sense to pay for iCloud services? Shouldn't they catch up with competition and readjust the pricing and amount of free storage?
