To be honest, the iPad works for me only for basic media consumption.
Everytime I try to create / develop my hobbys I find myself switching to my Mac instead.
For example, I wanted to backup my iCloud Foto library (400GB) on an external USB Harddrive. That may be possible with iPad as well. However I did it with my mac, as it is just copy and paste.
Further I think most serious stuff still requires a real computer (PC/Mac). Thats leads to the conclusion that iPad still limits my creativity and ability to get things done. For me iPad seems to be a barrier, not a tool.
