@turtlepower, for me "restriction" simply means no ability to work with my own files and folders, or even to work with files I get! on the IPhone, since iTunes is such a grabby monster, only wants it's own organizational structure (which is hell if you have eclectic musical tastes and don't buy in to all the artest, album genre rubbish), is near impossible to get out any files I actually have from ITunes, ---- oh and is a bloated mess to actually work with.
I tried using my IPhone as a media device for playing audiobooks and music for about two years, and it was such a struggle having to go through the tree of doom, create playlists, copy this and that etc, (and even then things may play in the wrong order).
compare this to my victor stream where I just bang in the usb and copy whatever folders I want straight across and they'll keep exactly the file names and structure I've given them on my hd.
There is no earthly reason the IPhone could not! use a usb file storage system and basically just let you browse files, even if it's ability to open certain file types was limited, accept that then, horror of horrors, you might listen to music or audio that you'd not! purchiced from Apple and the fat cats might not get their percentage, one reason why if you import or buy something into it's so difficult to get it out again.
That is quite aside from ITunes being a pretty cruddy interface for accessibility with it's trees of doom and lack of customization, indeed it's only as accessible as it is on mac Vo is programmed to only read certain portions of the screen. It was when apple killed the side bar headings in ITunes 12 that was I finally decided I had had enough and bought my Victor stream instead).
This is why I would never recommend the IPhone as a media device myself.
I am not sure how document handling works, I do know my brother uses ms word and documents to go on his IPhone, though since I'd have to carry my Bluetooth keyboard around with me for that to work it's not something I've looked into much, ditto with emails, I these days probably far faster typing than I ever was in braille, so things like braille keyboards etc aren't something I've looked into either. Plus
In the matter of documents, I will also admit I prefer myself to make my own backups on an external hd than trust too much to cloud storage, indeed the only thing I use Icloud for is for backing up my phone and contact data because it's preferable to tangling with ITunes.
For some reason, net browsing with vo is something that always seems to be a bit odd, in the way it says images, in the way it interacts with controls like list boxes etc.
for example I recall when I tried vo on the front of audiogames.net, instead of having the dropdown box with all the games on it as a dropdown I could enter, they were all present as links for me to flip through, which was a bit crazy. The way it reads images was also a bit nuts (I once tried playing core exiles with it). I('ll admit it is odd, since in html pages within programs such as the Cog and Hosted games or Apple's user guides Vo is %100 fine, though even there I will confess I sometimes miss the convenience of hot key navigation as it is far quicker to just hit b to get to buttons on a page than need to turn the rotor and flick down.
Then again I haven't seriously tried the internet with vo since my desktop broke back in 2014, so it's possible that things have improved, heck I do know the bug where I couldn't click on the "submit" button on this forum must be fixed, ---- that one I did actually report to Apple.
in general I tend to agree with Afrim that I like my phone for the things the phone does, running games and other great programs like blindsquare, ---- phoning people and making text messages too, but I wouldn't want to try to use a phone for all of the things I'd want a laptop for, eg, web browsing, emails, writing long documents, working on this site etc, heck, even shuffling around with the books on my Victor.
This why I'll probably be arranging a windows 10 laptop at some point in the near future.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
