I own a Lumia icon and have been really happy with it. The cut on Windows Phone is the amount of apps available. Since they are such a small share of the market, developers aren't keen to build for the platform - even though its completely wide open right now with little if no competition.
If Windows Phone had closer to the amount of apps Android and IOS have in their stores, the phones would be doing much better. Nokia makes a solid handset and the Windows Phone platform is the first not to copy Apple's design.
As for Windows 10 on Windows Phone - I was using the developer preview for a few days and its still really really buggy. It does have tremendous potential though and I'm looking forward to seeing them work out some of the bugs, there are a ton of really cool things coming:
