This day any software development company begin to change their way of distributing an installer, there was the day when we just need to download one installation file to use the software for like 5 or 10 months, but now every software is use word "update" to make us do the same thing over and over, i personally not a fan of those. One big issue is the internet connection, on my place internet isn't the strange thing anymore, everyone use it daily, but the problem is the cost to have it. It's way to expensive for small developer or the student, considering they don't have enough fund to spend. And yes the speed and the stability of the connection is another thing to worry about. But what could i say that was the reality, like or dislike we need to follow it.
