I haven't owned anything resembling a Nokia since the N95, but I am due to return following the release of the 950 (yes, I know it's not a Nokia, but it kind of is). Following on from my N95, my entry into smart phones went as follows:
1. iPhone (2G)
2. iPhone 3GS
3 iPhone 4S
4. Samsung Galaxy S4
Now, after each of those phones, my 'wants' and 'desires' for what a phone can do has evolved. When I left iOS behind, it was not only out of boredom for a locked down and limited UI, it was because I became frustrated with the lack of flexibility to expand the storage capacity of my 16gb phone without paying out a big sum on top of the original cost of the phone, even then the storage wasn't removable and neither was the battery. When Apple announced the iPhone 5, I saw sense that they weren't innovating as much as dangling a carrot in front of their users each year with small increments in added features, they were guiding users by the hand and applying limitations which really annoyed me. The point I decided to change is when the layout of the phone was expanded by one extra row of icons and they had now moved the headphone jack to the bottom of the phone, when they could have simply left it where it was and made the speaker at the bottom bigger and louder. After holding the phone, I was less than impressed, I became frustrated with the limitations of the Apple range and moved to Android.
The reason I chose a Galaxy S4 at the time was simply because of the amount of flexibility, not only with the Android software, but with the hardware. I could use SD cards to move from device to device, I could remove the battery and I could use OTG (Something that will be coming to W10M in the form of USB dual role) to connect my Xbox controller, as well as USB sticks etc. There was also loads of third party support for the phone, I had no trouble getting a large battery to expand my standby time. I was happy with the phone, despite having some technical issues with the Android software locking up and having to have the phone sent for repair twice, it seemed like the ideal choice for me. I'm still using the phone now. However, after reviewing my next option for my following upgrade, Samsung obviously decided to look at Apple's successful business model and they have now started with the limitations and gimmicks, cue the Galaxy S6.
When I look at the Galaxy S6, I simply see another fragile poster child for the Android platform, much like the iPhone is for iOS. Whilst the phone may look nice upon first glance, I dare anyone to drop it and see if it survives unscathed, whilst it might not get a crack in the screen, I have no doubt the shiny metal trim will have few scratches when it's picked up, making all that fine detailing that everyone is craving for in the new Windows Phone flagship absolutely irrelevant. This is why I'm getting frustrated with people complaining that the 950/940/Talkman doesn't "look" like a flagship device, but fail to understand the practicality of something that looks shiny that would be best suited in a case in the longrun. When I compare the S6 to the S4, I see a phone that is full of limitations with no expandable memory and no removable battery. Add to the amount of battery draining apps I have had running on the S4, as well as the bloatware that has been slowing it down, I've also grown bored of Android's inefficiency, despite the flexibility of the OS.
After having used my my girlfriends Lumia 640 and lurking this site for many months, I've come to the conclusion that Windows Phone is where I'm headed next. I'm an Xbox One and Windows 10 PC user, so maintaining some consistency across my devices has contributed to my research of Windows 10 mobile. I admit the platform itself is still missing some features and various apps, but the idea of having cross platform Xbox support, setting reminders on Cortana on my PC to sync with my phone, using continuum via the miracast feature on my Xbox, having what is usually regarded as the best quality camera on the market for both image and sound recording, a rugged enough design that is less likely to break after a fall, as well as a very nice UI, just sounds good to me. So, yes, I will be getting a Windows Phone next.
