Skype users, keep an eye on that terms of service and “end user license agreement” each time you are forced to install a new version. Expect subtle (or not so subtle) changes. You may not like them. Your options will be few. Think next time before choosing a proprietary product with proprietary protocols, blah, blah, blah… (head explodes…)
Oh, and even though I downloaded Skype 4 or 5 times, it should only count as 1 in my book… Keep that in mind when doing the math.
