Looks like a pretty nice setup. What's nice is you know all your information's on the phone, so when you need to travel light you can take just that with you and be confident you have access to your work.
Plus, working with that magnifier and little screen isn't going to be good for much other than writing - which is a great way to force yourself to focus on writing. (This is why I love typewriters, but they're a lot heavier.)
Proof will be in the pudding. Once you've got it set up, how much do you actually use it? Looking forward to the follow-up post!
