I have the "Apps" messaging and stuff on two tablets without Skype installed so to the OP you do not need Skype to use messaging etc.
I do have the desktop program on my desktop as it allows me to "manage" Skype.
To the others, I am at a complete loss to understand what MS have done with Skype over the last year or so, so badly managed and so badly communicated, you have the staffers over on the Skype forums just shutting up shop when anyone asks an "Awkward" question, shambolic.
I don't know who is to blame, is it MS? is it the management at Skype? maybe a combination of the two, but if they don't get their act together soon they will have managed to kill off a brand that had complete dominance.
I decided to use Skype for my family communicate and make things simple for my wife, but within weeks it was laughable, "Well no you can't view pictures on this device, to do that you need the other version", but that doesn't work on that one but you can't use the app as they are killing it off, and so it went on.
Come on MS, make it work, make it easy to kill dead accounts and take back ownership of hacked ones that doesn't count on you remembering when you first signed up for Skype (to the month for something you may not have used for several years), you have to tighten up on spam and then give people the choice of an app or full Skype.
