Hardware, Embedded Systems And yet another item on the iPad? Are we serious? Yes, we are, since this one is about something that even geeks who aren't interested in the iPad itself should find intriguing. Steve Jobs said yesterday that the iPad is powered by an Apple A4 processor, but contrary to what many seem to think - it wasn't designed in-house at all.

RE[2]: windows 7 on ARM?

It probably has. Windows NT was originally written on a custom architecture as to ensure no platform-specific code would seep into the codebase. I'm sure Microsoft's major products (Office, Windows) have at least some variants running on ARM.


Microsoft probably does have versions of Windows running on ARM. This will not help them.

There is a large corpus of x86 binary executable Windows software out there in people's possession. This consists not only of things like drivers for their printers, cameras, phones and other miscellaneous pieces, but it also consists of unused licenses for desktop applications such as Office (for example, they have installed so far only one copy of Office from a three-license pack).

In addition, there is all kinds of specialist software, distributed as x86 binary executable only, from all kinds of sources other than Microsoft, which people expect to be able to use. An example might be a Windows utility, designed to run on a laptop, to set parameters on a high-end audio mixer console.

Finally, much of Microsoft's historical lock-in attempts revolve around tie-in to the x86 platform. A good example of this is ActiveX:
http://blogs.msdn.com/iemobile/archive/2007/06/20/ie-mobile-support...
You can’t run Windows based ActiveX controls on a Windows Mobile devices. (X86 and ARM processors are too dissimilar.)

...

Windows Mobile IE Mobile does not support automatic download of ActiveX controls. This was a deliberate decision made to increase device security and to avoid the first point (a X86 version of a control being pushed down to a ARM based device)


When they opt to purchase any Windows machine, people expect to be able to use all this software.

People won't be able to use any of this type of software if they purchase a new machine which runs Windows on ARM. So people will have to switch to a new set of applications if they are going to buy an ARM-based device.

If they are switching to a new set of applications anyway, this represents an ideal time for people to just ditch Windows and finally be rid of all the problems and encumberances it brings.

This is true for other OSs as well. For example, most comercial software available for Linux is x86 only.

So unless you have very general use cases, like most home users do, you are not going to migrate to other processor architectures.

It is true to some extent for Linux. Only on Linux, of all current desktop OSes, however, can you get a comprehensive set of applications for any architecture. There are upwards of 25,000 packages in Linux open source repositories.

One of the few applications that is commercial ONLY for Linux would be Varicad:

http://www.varicad.com/en/home/

Although there are other Linux CAD packages, Varicad is AFAIK the only one which can process .dwg files.

Having noted that, however, it should also be pointed out that high-end commercial-only applications such as these aren't really in the picture when it comes to tablets and netbooks. One just isn't realistically going to be running Autocad or Varicad under Windows 7 on ARM, either.

Everything else ... every lightweight application class that one might actually WANT to run on a low-power ARM machine ... already exists as open source and is already ported to ARM for Linux.

But unlike on Windows systems, on Linux closed source apps are a rarity rather than the norm. I have a number of Linux systems which don't have any closed source applications on them at all.
