At least that's what I feel. I've been a long time iPhone user. Got my first iPhone two months after they came on sale, and been using them ever since... ...until late last year.
I've had several Androids "on the side", but none of them felt comfortable to use. Last one was a SonyEricsson from last summer with latest and gratest OS version. It was nice, but still no cigar. It still suffered from the same fragmentation of the UI that all the Androids before it, although to a lesser extent. But still, awkward to use compared to the iPhone.
But before Xmas it was time to upgrade my phone once more and I was thinking about iPhone 5, but decided to give Windows Phone a shot. I got the (now old) Nokia Lumia 800 which only had WP 7.5, as it was cheap and wanted to see where Microsoft had gotten with WP. - I was amazed! - For the first time since buying the very first iPhone, I felt like there was something new to a smartphone. It had gotten smarter and easier to use.
I know the shortcomings of the Lumia 800. No multitasking for one. But I never really used it on iPhones either. It can play music while doing other stuff and receive calls/messages whatever I'm doing, and that's really all I want from a phone's multitasking. Also the Nokia's navigation was really something. All the world for free! And it's as good as any standalone or phone navigation I've used (TomTom, Magellan, Navigo). I also love the AMOLED display! Black is black and white is white and typography makes it easy to read. And you can easily read it in direct sunlight. - But most important of all, the UI is always logical and things are where I expect them to be. Also it feels actually faster to use than the old iPhone 4S.
What can I say. My iPhone feels outdated, and that was done by a phone that has been sitting on the shelves for over 6 months! Ok, the iPhone 5 is newer with some cool gadgets, like the camera. But it's still exactly the same UI as iPhone 4S. And the UI is just outdated. - Or feels like it to me! Also I have to say I haven't owned any newer Samsungs, but some fiddling with them really didn't make them stand out from the rest (of the Androids).
After all that, I'm still sticking to my MacBook for laptop and the iPad 2 is going to be serving the tablet needs for some time to come. But when I do upgrade my tablet, I will give Windows tablets a go. Maybe I'll switch, maybe I'll stay with iPad, don't know before I'll try. - As for laptop (tablet won't do everything I need), I see no reason to go Windows. - And when I upgrade my phone again this year, I'm thinking I'll wait until Nokia gets their second generation WP8 phones out, unless Apple will finally do a full makeover to iOS and not only catch up, but take the lead once more. I don't know what it would be, but it'll have to be something damn awesome!
