I decided that it's time to install an e-mail client on my computer so that I don't lose old messages on my Hotmail account due to expiration. (I already lost all the e-mails between me and my late wife, and that continues to gnaw at me.) I use Thunderbird for other accounts and, while I could add Hotmail to it, I prefer not to. So I poked around, and found a freeware client called eM Client. Downloaded it and installed it, and it made me obtain a license (free) with an authentication code.
That got me thinking -- In addition to my primary desktop computer, I have a couple of other desktops (rarely used), a couple of laptops (at least one frequently used), a netbook, and a Windows tablet. Since when on the road I would probably have either the netbook or one of the laptops, plus maybe the tablet, I want to have the same e-mail client on those. So I contacted the company that puts out this software. Their response was that multiple installations is commercial use, and to do that I would have to buy a multi-user license. Even though it's only me that would ever be using it.
So I uninstalled their program and installed a different one.
How can anyone today seriously believe that people would only have ONE computer they would be checking e-mail on? I mentioned this to a friend and his response was, "Hell, I've got nine computers at home -- but I only use seven of them."
