There are two critical differences between Microsoft's lockdown and the status quo of the ARM tablet market:
1. The status quo in the tablet market is for hardware manufacturers to decide whether to lock down their boot loader. Microsoft (who is not a hardware manufacturer) would force hardware manufacturers to lock the boot loader of any ARM devices running Windows 8.
2. Not all ARM devices are tablets and phones. ARM-based netbooks (i.e. miniature general-purpose PCs) have been available for a long time, and there's an expectation that you can install whatever OS you want on a general-purpose PC. Microsoft's ARM lockdown rules (as quoted on the previous HN discussion of the subject) would apply to devices that people expect to be able to customize.
1 - Yes, Microsoft will force vendor... if vendor wants to ship their device with Microsoft OS. That's how they structure their deal with vendor. I seriously fail to see the problem here: Windows 8 ARM doesn't even exist as a commercial product and all vendors are happily shipping Android devices left and right. So, come Windows 8 ARM tomorrow - what, Android will suddenly cease to exist? Does Microsoft provision prohibit vendor from shipping same/similar hardware without logo with other OS installed? This happens right now with phones: same hardware goes for both Android and Windows Phone, no questions asked.
In my opinion, this whole "logo requirements" thing is blown out of a proportion: there's no commercial product with Windows 8 ARM, almost all Android devices are locked down, yet Microsoft gets all the heat.
2 - Presence of a keyboard doesn't make toy device a lesser toy with same toy rules applied. Besides, my $20 says that the moment we see MacBook Air on ARM or Windows 8 ARM netbook, we'll see Google revitalizing their Chromebook story or shoveling Android onto netbook devices (ASUS Transformer anyone?) and vendors happily supporting them.
