Regarding the issue of "rich multimedia" clients like Viber and WhatsApp, it seems to me that the incumbent operators start to get concerned about these applications taking a big dent in their SMS-Voice revenues.
They are all commited to a new type of applications called RCS-e (Rich Communications Suite - enhanced). Google for it to know more about it.
There are many RCS-e clients from many vendors (including Nokia, Ericsson and others), and I think it would be nice to port them to maemo.
Some of them are open-sourced as specified here before... http://talk.maemo.org/showthread.php?t=70433, altough I think this doubago stuff is a bit outdated.
Anyway I think an RCS client ported from linux to maemo would be nice and expand the lifecycle of the product.
I dont know why people start talking about the things they dont know.
I am sure all of the above who dont like viber are actually the ones who have never seen/tried it.
I can keep my N900 for some more time if I get Viber on it
I am so sorry If I will be mean to some of you guys but I cannot stand anymore and not say something !!
I really don't care anymore of those mambo jambo geek bullshits. We all wants our life to be simple why maemo developers haven't still developed Viber or even SIRI ? Probably just because they don't have paid to do something ok I understand that, what I don't understand is why they think are the smartest ones ?
