What are some of favorite apps?
There're many… 1Password (version 4 looks incredible), Deliveries (I rely on it for tracking packages from eBay), Buy Me a Pie (the best grocery list I've used), Panamp (music), Light (yes, it's a flashlight app; I also have a good "hardware" one), Verbs (IM), Partly Cloudy(weather forecast), Fantastical, Chrome, Tweetbot, Reeder, Sparrow…
Which app is your guilty pleasure?
Letterpress (you won't tell anyone, right?).
What is the app you are still missing?
I'm still looking for good music and video players which are not chained to iTunes. I just want to listen to the music on the go, not sync, re-sync or move my music collection to iTunes (which doesn't play well with NAS).
How many times a day do you use your iPhone/iPad?
None to every few minutes, that really depends on what I'm working on. Sometimes I prefer to leave all my gadgets on a shelf.
What is your favorite feature of the iPhone/iPad?
Pocket-sized Web browser. Seriously, this covers most of my needs. My iPhone is mostly used as a web browser, news reeder, mail checker. And yes, it can make calls (killer, app, huh…). iPad works as a book and news reader and a portable game console. I tried using these devices for writing short texts or drawing and still prefer paper and good old iMac.
If you were in charge at Apple, what would you add or change?
App switching. Current solution (icons) is even inferior to one of Palm's webOS. Notification Center. Either you do have widgets (weather/finance, anyone?) or you don't. Camera app. It's now incredibly cluttered. Lock screen. Another design abomination… Siri. She's unbelievably slow, stupid and useless. iCloud. There's a lot of space for improvements. App integration. Let's just face a simple fact: files need to be shared between apps. And, most of all, iBatteryLife. No complains about iPads, but hey, I don't need a razor-thin iPhone, I need it work longer.
