Learn to write apps for other platforms - it is the future ;)
Adapting to use a new gadget always has a learning curve and takes time to become second nature. Those few seconds over the next few weeks are nothing compared to the hours of misrouting and the cost of taxi's rather than the public transport I endured during the first few days of iOS 6 and apple maps experience.
I love the screen size of the Galaxy and in this respect it is better than the iPhone (4&5). I was concerned about the less solid feel but my colleague has a 5 and it is noticeable lighter than the 4 which surprisingly is an unwelcome feature taking It down to the Galaxy's feel. It doesn't feel like you are holding a quality item any longer. The new black finish is so scratched now it looks older than my 4 - by years!
At the end of the day it's a smart phone - smarter than the apple it would seem - it will do for now - it may even out live the iPhone 5 if apple take this latest offering the way of the iPad3 and the soon to be dead, iPad mini... - gasp really? Yes -apple are now of the belief that iCustomers are cash cows. As soon as they can, the retina display iPad mini will be on the shelves as will the iPhone 6 - which will hopefully not "fit in one had" and by this time I hope google will have an app working on iOS 6.9
Personally, the iPhone 4 was the perfect size for me *( I now find, after a month of having an iPhone 5)
It fit sideways in a shirt pocket, so did not fall out when I bent over.
I could also use it with one hand, thumb able to reach the extremes of the screen, without shifting the phone around. The iPhone 5, I can't do that any more. I find I constantly have to shift the phone slightly to reach the top left corner now.
Anything bigger than an iPhone 5 is like a laptop to me, they simply don't fit my shirt or pants pockets. Might as well carry a purse or backpack for them.
