So you don't plan to support Windows 8.1 or above? The changes made here aren't going away any time soon.
Dot, he was referring to the folks he is supporting - lots of XP, and some 7. If they are enterprise customers, they are going to be largely unwilling to upgrade (whether they are under a SoftwareAssurance or other enterprise contract or not) due to training costs - I can't exactly fault enterprises for being unwilling to spend on training for a new OS when there are other priorities. Then there IS the issue that there are a ton of XP users - how much of the HARDWARE is just plain deprecated, and couldn't even run Windows 7, let alone 8? If the hardware can't run 7, it can't run 8 (especially since the reverse is also likely true) - that means that just in replacing XP with 7, there are hardware costs that WILL be incurred. If you want to avoid training costs, going to 7 (not 8) is a safe bet - and one thing enterprises like to do, especially in a shaky economy, is play it safe. I get that much.
My issue with the critics is the smoke-blowing and outright dishonesty over the reasons for their criticism of either Windows 8 in general, or ModernUI in particular. If you are uncomfortable with the UI change, say so - there's no harm in that, and I won't hate you for it; just don't blow smoke up my posterior and try to pigeonhole the UI as "touch-only" or "touch-first" - that is no more true of ModernUI than it is of Android of today.
