As far as domains go, that really isn't much concern to home users. It's also not much of a concern over the other ARM based tablets since none of the ARM based tablets (Windows RT, Android, iPad) run windows legacy apps.
Which would mean that many companies would not consider them for their employees then. That is large market of the traditional MS market that they are missing out on.
And it's exactly this kind of defense of the walled garden that breaks my heart. Do you even realize that your arguing for a future where the OS manufacturers decide what software you're allowed to load on all your devices and computers? Do you even realize what a change that is from EVERYTHING WE EVER STOOD FOR before the 21st century???
And do you realize that you are arguing for a future where you decide what is in the best interest of everyone? You want to install your own software from anywhere? Buy an Android phone. No one is stopping you. You are the only one here advocating against freedom.
The walled garden exists and has been accepted because a major problem with the alternative. Generally, consumers are not tech-savvy; they don't want to hack with their OS. They want it to work. Apple offers that to them.
Do you REALLY want Apple, Microsoft, and Google deciding what software you can and can't use in the future? Seriously? Because that's what you're arguing for.
You do realize that Android is from Google right? And you can choose not to use anything from them. You want a phone completely free of them; start a company and start manufacturing. You don't have millions in capital? Well, that's not on any of them is it?
I thought MS was bad back in the 90's. But *NOTHING* that MS ever did scares me as much as Apple's walled garden concept, and the potential future that it portends. And to see someone with a six-digit UID actually defending it on Slashdot scares me even more.
Then don't use any Apple products for Chrissakes sake. I don't own a tablet because I don't want one. I don't own a Windows PC machine because I chose not to own one. I own a very old Mac because it is the only machine that I can run Windows, OS X, Linux, and BSD all on the same machine.
The main difference between MS in the 90s and Apple today is not stopping me from using other platforms. If you use their platform there are limitations (as there are with any platform. Apple didn't go out of their way to harm their partners and competitors like MS. See Java. See Netscape.
For years (especially under Ballmer), the problem for MS has not been their strategy per se but their execution. Getting people off XP is a good thing; not helping people with it is an execution fail. Of course there are some people that cannot upgrade as their hardware is too old, but acknowledge this. Not recognizing that people dislike the solution (Win 8) is another fail. If they had done this with Win 7, it wouldn't be as big a deal.
We've seen this lack of execution again and again especially in the mobile area. The Zune wasn't a bad idea. It was years late and didn't offer many advantages over the iPod. Buying Danger to get into mobile phone market was a good idea; being 18 months late and releasing a buggy phone that wasn't a smart phone but cost as much as a smart phone was a fail.
To understand a program you must become both the machine and the program.
