I would love the iPad to be my one-stop solution for tablets. Someone asked where the practicality in owning two tablets was, and I'll tell you exactly why I would own two tablets. The devices cannot actually "do everything" I need. The iPad is limited on storage space, but has tremendous selection in applications. The iPad cannot install other software, but it has tremendous battery life (comparative to my laptop).
In some ways, the iPad I have replaces my laptop, and in others I can't stomach doing certain tasks on my iPad (I do not jailbreak my devices) like online banking, and secure transactions. I would never do my taxes on my iPad, I don't feel like word processing and document creation, file browsing is something made for the iPad's interface. All of these things I require the use of a PC for. In Feb 2013, I will be replacing my laptop with the Microsoft Surface Pro for those reasons, because a one-stop solution for tablets these days does not exist. The iPad for me will always be a tremendously powerful and beautiful multimedia device, but I don't feel like I'll ever be comfortable with doing EVERYTHING from my iPad.
If Apple could find a way to actually turn the iPad into the likes of their Macbook Pro's, etc. that'd be amazing.
