It 's nice to see microsoft is bringing back the messagaging app. It was pulled from windows 8 after the 8.1 update. Probably because not enough people were using it. I'm curious to see what happens with messaging.
I'm not sure if microsoft can pull off adding sms. Whatsapp is already trying a web based app. There are issues with online phone authentication and security etc. Technically I could imagine that it could be done easily, but I think microsoft is going to run into a lot of regulatory issues with carriers and countries. Makes me wonder how Apple pulled this off.
A more bigger concern for me in skype. It's a great service, but in my surroundings skype has lost traction and popularity over whatsapp. I hardly know anyone in my private world that uses skype video or calling, private or businesss. skype may have a global significant userbase, but I think it is a huge omission to leave out huge platforms like facebook chat/messaging and whatsapp out of the equation. I think that if microsoft could at least try adding those, the messaging app could be productive and cool on a global scale. I seriously hope microsoft would consider this. This was also the issue with messaging and userbase with the app in windows 8.0. I hope they learned from that. Skype alone will just not cut it. Too many will still be left out of the conversation. With messaging and communication it is my belief not to bet on a single platform, but proactively combine social platforms into one messaging platform. Messaging apps should not be a battle of the platform OS battles, it should cross platforms. Only then will it be truly useful, fun and productive.
