For you, but not for everyone.
You see I have nothing against new things, I do have something against poor implemention of new things. Why I am afraid? Looking back in the history of replacing apps, MS eco system is not pleasant. Biggest drawback Zune and the new Groove that went though name changes twice and redesign. Not even now it's not finished.
So... they launched Windows 10, they brag about messaging and skype integration, first releases were awful, with time it became better, now they have a pretty stable messaging + skype app (yes, it works, maybe not for you) and what do they decide? Kill it and start again with new Skype UWP
What does history tell us? That the first releases (probably the first year) the Skype UWP will be awful. We go again in the cycle of Microsoft stupid decisions of rebooting a product over and over as soon as it reaches stability.
For the life of me I cannot get why they are doing this with some of the apps/services.. I suspect someone is brain damaged and in charge of Microsoft decisions, cause otherwise there is no logical explanation. I mean when the community argues over and over about the Zune removal, you must be retarded to do that again with another product.
