When the iPhone was released in 2007 with a "desktop class" web browser, it was widely praised. You could view entire websites on a mobile device. Coming from the days of WAP optimized sites on my Motorola Q, this was incredible. If we fast forward to 2014, Mobile Safari has become the app that is holding the iPad back from becoming a fully featured laptop replacement for a lot of people. While Mobile Safari is fast and loads website reasonably well, it cannot upload and download files. It can upload pictures, but that is it. Mobile Safari needs a way to upload and download any type of file into iCloud Drive (a mirrored from the Mac downloads folder).
Last week, I had to upload 2 PDF files to a WordPress powered website. This is something that iOS should be able to handle. I should be able to save the PDFs from my email to iCloud Drive. Mobile Safari should then let me upload those files into a browser upload window. iCab Mobile can upload files reasonably well, why can't Mobile Safari? For iOS to mature as a platform, these are the type tasks that it must be able to do.
Until then, I'll use this app.
