I think it is kind of like buying a new ANYTHING. Some folks will buy a new model as soon as it comes out.
Some will wait a few months to see if anyone else is having problems with it. Whether it is a vehicle, electronic device, refrigerator, MS-Windows, new online service, etc. As more folks use the ANYTHING, more issues will be found. Fortunately with something like operating systems, changes/fixes can usually be made fairly quickly. mrc
