When I was in the market for an iPad a friend of mine recommended I save my money and buy a desktop computer instead - this friend knows that my hobby is website/graphics creation. When I asked why, his reply was; "iPad just isn't powerful and there's so much it can't do".
Today I re-wrote my website from the ground up and this is how I did it.
* An FTP client (App Store) - used to connect and navigate the folders and files on my server (I'm in the US, my server is in the UK) as well as some file editing.
* Safari (by Apple) - used extensively for testing my edits.
* Photos (by Apple) - used to crop and upload photos.
Note: I learned how to design webpages years ago in a text editor so I'm comfortable designing whole websites without the need for WYSIWYG editors. Doing everything manually is simpler and gives me more control anyway.
To be honest, all of this could have been done on my iPhone 4S, but this is an instance where the larger screen of the iPad mini was a definite plus.
iPad not powerful? I beg to differ
