Always makes me laugh this argument over the apps. I've had my 930 for a year now and haven't missed anything despite spending the previous 4 years on Android. Truth is, unless it's a favourite game or something you're not likely to miss anything that you won't find a decent, if not better and cleaner, equivalent for on Windows. That's my experience anyway as a business user.
I think there are a quarter of a million plus apps now on Windows, so you need to think about how many you really need and disregard review after review after review brainwashing everybody into thinking Windows phones are inferior because of the app gap. Take the dross out of android, the 1000+ flashlight apps etc. and you will find the gap isn't that big after all. I do have to concede that a lot of major businesses may not be there (my bank is thankfully and their app is way better than either the android or iOS versions too), but now we have the speeds for a decent internet connection it is far less of an issue than it was even a couple of years go, and it's just as easy to use most firms' main website as it is to use their app, especially as most have mobile web versions anyway.
Oh, and personally I prefer using both Facebook and twitter's sites on my windows phone but like anything it's a matter of choice but my point is that the app gap issue is totally blown out of all proportion simply because of the number of times it is brought up. The reality isn't anything like as bad as the perception is made out to be.
