Dear All, 1. I asked a similar question recently on Apple Forum here. 2. I personally understand perhaps the reasoning, not to debate here. It does pose certain challenge in certain scenario. Just need to know more basis due to future work area deployment. If you need to ask, I only have one Windows 8 computer at work now and I have never touched that unit from start because the user is particularly sensitive towards that computer. 3. For Windows 8.1 (completely new device), is normal system /application software updates going through App Store? Do you need to enter credit card number in order to complete the update process? Or is it very similar to normal Windows 7 style traditional Windows Update?
