Well... I did get to use it on a test in Physics in high school, but only because my TI-84's batteries were dead and I had to use a TI-84 Emulator on it... And the teacher sat behind me the whole time...
Point is you're better off using the calculator and keeping a spare set of batteries around.
They are not totally different at all.
Windows 8 is a super set of windows RT.
Windows 8 is windows RT + desktop mode.
Anything you buy for WinRT will also just work on Win8.
However, that's not correct.
Windows RT runs on ARM processors, and as a result all binary files (programs) have to be compiled to run on ARM.
However, Windows 8 runs on what is called x86 processors, and it's binary files have to be compiled to run on x86.
And that's just the most basic difference, that completely ignores any other software differences.
What you buy for Windows RT will not just work on Windows 8.
They're set to release information on their first phone in November, it'll be a linux phone like the Nseries phones, and while it's not likely to have the massive app market for native apps, it should do all the things you say you're looking for.
They're also saying it'll run android applications, but that's just icing on the cake for you.
I'll admit to being biased as a N900 owner, but perhaps you'll be interested to see what they offer? At the very least to compare to the windows 8 phones out there as well.
Slashdot: News for nerds, stuff that matters
I still have my n900. Gee, what could have been, if they hadn't been such cowards!
As someone still sticking to his N900, I think I'm going to pass on this latest offering.
That said, have you looked at what Jolla, a company of ex-Nokia employees is doing with MeeGo, the successor to the Maemo OS which our N900s runs?
Personally I'm looking forward to what they have to offer.
However, as a US citizen the radios they choose to put into the phone may prohibit me from using it, as I'm not keen on switching from TMobile because of my grandfathered data plan.
I'm also concerned about if their phone will have a physical keyboard or not, but it is said that there will be a developer edition, which may be more to my liking.
They're also saying that the Jolla phone will be able to run Android applications, and if so that'll be an exciting development:
And again, you may have missed the point, which I only initially called you out on because you decided to make a comment that was irrelevant to the issue at hand. It does not matter whether it is Google or Bing, it matters that ISPs will make network upgrades in such a way that one may get an upper hand over another.
It has nothing to do with walled gardens, I only made my comment to show that you could have made a better argument against his actual point, not pick on him a small detail.
All that said, I am glad you have continued to clarify your point, even though I think you are not arguing on the point at hand.
