Ok smart boys, what's the point of delaying getting in the tablet space by two years just so you can have the same kernel from PC to tablet to phone? The user doesn't care about the kernel. Only geeks do.
Microsoft have already demonstrated on numerous occasions the full version of Windows 8 running on ARM hardware without any of the problems you seem to suggest would have to exist.
Really? Even TI with their latest and greatest processor weren't ready to go on camera with a demo: http://ces.cnet.com/8301-33363_1-57358767/ti-offers-rare-demo-of-windows-8-explorer-on-newest-arm-chip/
And there's more...
Is Microsoft waiting for some special event where they show the rest of the world W8 is ready for ARM? What's the big secret?
As with underpowered netbooks I'm sure W8 phones will be full of compromise (none of which will be coming from Microsoft). You'll need the latest and greatest of everything in order to get modest performance on a phone. And let's not forget about battery life; being ARM doesn't mean the OS gets a free ride to long battery life. They had all that with WP7 and kissed it and two years away just for some nerdy goal.
I predict Microsoft will go from bragging about how WP7 doesn't need a multi-core mega phone to boasting (and requiring) WP8 having multi-core mega phone creds.
And as for Linux the big difference here is two fold:
- Linux has been running on routers, set top boxes, and phones for many, many years. This is the Windows kernel's first time. Good luck with that. Maybe they should call it "Window Phone 8 - The Virgin Edition" WP8-VE for short of course.
- More importantly Linux doesn't care how it's being used -- it's not part of a greater strategy. For Microsoft "Windows Everywhere -- Even If It Sucks" seems to be a huge roll of the strategic dice when it really didn't have to be. (Again geeks rule the day here.)
I'm not trying to get into a pissing match on Linux vs. Windows. I'm just saying Microsoft made a big mistake not sticking with WP7, Silverlight, et al for tablets and getting to market two years earlier.
Now taking this W8 strategy down to the phone makes no sense as it doesn't buy them anything with user and it's my prediction it's going to make for a woeful phone experience to top it all off. I'm hopeful Nokia is successful in retraining retail on selling WP and getting their sales numbers up. Now along comes Microsoft with the new WP8 and tops those efforts with...wait for it... a phone that runs the same kernel as a PC. Exciting days ahead I'm sure.
