I know a lot of us are waiting on Windows 10 devices before we do anything else. One of the major complaints about Verizon has been their glacial pace for allowing customers to access updates (even though the other carriers have had the same updates for quite a while.) Thankfully, Microsoft has heard our cry for help and announced that updates will come directly from them instead. The bad news is that if you want to keep your current Windows 8.1 device and upgrade it to Windows 10, you'll have to wait for Verizon.
