Formatting is a hurdle. I'm kind of up in the air on my system right now. Docs to Go became unusable on my 2nd Gen after OS 4, but performs brilliantly now that I got the 4thGen iPod, but they made it so you have to hide keyboard to make formatting selections which is retarded. It doesn't support shortcuts besides arrows on external keyboards yet (ever?).
If you just want to get words down and add formatting in later, Notes is just as handy. No formatting in Notes -- despite the funny font, it doesn't display rich text, even if you view a synced note from Mail app I think. Notes is all text and then it superimposes links on detected content as far as I can tell. What I can't believe about Notes is that you can't add an individual Note to the Home screen, that is irksome.
Oddcult what iPhone model are you on? 3G and below lost OTA Notes sync in 4.1 update
Notes works fine, its best feature being the automatic synching. I proof and format everything on my laptop anyway, so it works perfectly well for what I need at the moment.
I'm still enjoying using the iGo UltraSlim Stowaway keyboard, but they're going for silly money now. No one seems to have realised that there's a serious market for secondhand ones and re-released it, or something similar.
I'd recommend Bluetooth over a hard dock, as you can pick up the phone easily if it rings, or to go online, or do whatever, and as I've got the thickest otterbox case there is, which gets in the way of a lot of docks, it doesn't need taking out of it to slot in, and it means I don't have to worry about anything getting spilt on it, or it getting knocked over, if I'm writing in the pub or coffee shop.
I'm on 3GS. My friends sold me on just purchasing the basic Apple wireless keyboard. It's a standard keyboard rather than a tiny one, but it fits in my bag fine and it's very light.
Unfortunately I bought one from an Amazon Marketplace seller and the one I got in the mail was defective. And the seller hasn't responded to my emails. But the other iterations of this model I've used were great.
I got my Apple wireless keyboard replaced. It's been great so far, but this week I'll be roadtesting it for real. I've got a couple of text apps that connect directly to my Dropbox, so it's all very very convenient.
My apple wireless keyboard's been working fine for a few months now, so I'm pretty sure you're safe, Brandon :) Just be prepared for people to pop out of the woodwork demanding explainations as to what you are doing, and saying "Is that .....a keyboard.... for your phone? Is it?"
