I recently decided to get a case for my iPhone 5s (wanting something a bit more rugged and that I'm happy using in the rain). So I ordered a Lifeproof Nuud case (makes the phone shock proof from up to 2m, waterproof to 2m, isn't that big, doesn't put something over the screen, is easy to get headphones on/off and still allows touchID to work (and runs the iOS apps that I still can't get on android or WP).
Wow- this feels like a totally new device. It still fits comfortably in my hand and now I have no qualms about dropping it or using it in the rain. Yes the bare iPhone is slim and slips into any pocket. But I like this rugged new iPhone: touchID works perfectly, and everything else (like swiping up the settings for quick access to wifi, bluetooth, torch...). The only downside is trying to take the case off (external speaker sounds a bit more echo'y than before).
I did consider the iPhone 6+ but will wait to try it myself. Though perhaps I don't now need a new phablet. I have my Nokia 1520- which has a stunning screen, great battery life, character and is an enjoyable experience every time I use it- more than any other phablet I've used (including the Note 3, gFlex, HTC One Max, Xperia Z Ultra...). I'll try out the Samsung Note 4 as well and there is the upcoming gFlex 2. (The first gFlex was the most practical phablet I've used, certainly for one handed usage- and apart from being more comfortable and practical than my Note 3, also gave me about 40% extra battery life).
If I didn't already have a phablet the other device I'd consider would be the LG G3 - preferably with WP which is definitely growing on me (going back to my android devices is leaving me flat in comparison. And iOS, well that's not an OS that really tries to get between the user and the app).
So, it looks like I've saved myself a lot of money- perhaps it's time to buy a dishwasher.
