Another Apple-to-switch-Macs-to-ARM post. "Apple engineers have grown confident that the chip designs used for its mobile devices will one day be powerful enough to run its desktops and laptops, said three people with knowledge of the work, who asked to remain anonymous because the plans are confidential. Apple began using Intel chips for Macs in 2005." No idea when Apple will make the switch, but they will do it. I'm thinking 5-10 year timeframe.

You would need a Mac with a touch screen for the best effect, but I don't think that would be very practical. It would be very hard on your arms. Even on a laptop it wouldn't be very comfortable.
I have a magic trackpad and I like it, but using it to control on-screen iOS apps would be guessing where to press your finger. Better would be to use the mouse pointer, but them multi touch wouldn't work.
Making a fat binary that includes version for the iPhone, iPad and a Mac would be a terrible waste of space.
Desktops and laptops are a different thing than mobile devices like phones and tablets. I like my iOS devices, but I would hate it if my Mac became a restricted device.

A number of ARM CPUs would make a powerful machine, but (and I'm not expert) I don't think that would help much if the computer was doing one single heavy task. Multiple CPUs/cores can handle multiple processes, but I don't think they can join up to speed up a single process.
But I wouldn't mind being wrong this time.
Applications can use threads to take advantage of multi-CPU/multi-core sysems. This is not an issue specific to ARM and is very much an issue with x86 based systems as well.

I think they can run iOS apps on a Mac right now if they made an emulator, like they could run PPC software on Intel machines.
...but you already have a iOS device emulator for Mac OS X... for 5 years now.
http://www.youtube.com/watch?v=VvOs6UpVJes
they (Apple) do not even call it "emulator" but rather "simulator" (since there is nothing to emulate! e.g. ARM
) so this is not a issue (or purpose)! - switch Mac to ARM and than run iOS apps on Mac.
you can do it today.
--- but
take a look on today Mac OS X; you can burn CPU 100% if you do:
1) rendering
2) zip/unzip stuff
3) run Adobe Flash
4) some heavy PhotoShop-ing
5) Aperture
6) complex javascript/html pages
... and all this stuff could run even faster on GPU! (e.g. new Aperture heavy relies on GPU!)
on other hand, for:
1) chatting
2) skyping
3) typing
4) exceling
5) emailing
6) ~browsing
you do not need nothing faster than todays ARM!
all professional (content creation) application could benefit more from GPU than from CPU in future (as we have more and more advanced underlying infrastructure: compilers, languages, frameworks...)
...and one very important thing for future: it is easier to double GPU power than CPU power!

At an event earlier today, Microsoft unveiled the next Xbox - the third model, but confusingly named Xbox One. The big focus was TV, integrated Kinect, and all the other stuff we all expected to be forced down our throats. I think it took them 25 minutes to actually come to what should be the core of the story: gaming. Nothing groundbreaking in the gaming department, except for how Microsoft intends to handle the used games market and borrowing games from friends: pay up, buddy!

The day has finally come! Jolla has finally announced the launch device for its Sailfish operating system - and by god this is a looker. It's decidedly different from other phones out there, but it has good specifications and carries a relatively reasonably price tag - EUR 399, and it's up for pre-order today, shipping in the fourth quarter of this year.

Why does Google get so much credit in the technology industry? Why, despite the company's many obvious failings, do many geeks and enthusiasts still hold a somewhat positive view on the all-knowing technology giant? A specific talk at Google I/O this week provides the answer.

"Windows is indeed slower than other operating systems in many scenarios, and the gap is worsening." That's one way to start an insider explanation of why Windows' performance isn't up to snuff. Written by someone who actually contributes code to the Windows NT kernel, the comment on Hacker News, later deleted but reposted with permission on Marc Bevand's blog, paints a very dreary picture of the state of Windows development. The root issue? Think of how Linux is developed, and you'll know the answer.

This is one of those news items that's fun to write, fun to read, fun to comment on, and where no one will be able to say anything unkind. It's all just one big ball of awesome fluffiness. TuneTracker, the BeOS radio automation software, has just released something very special: TuneTracker System 5, the first version designed entirely and specifically for Haiku. In fact, it actually includes Haiku in the software package. Better yet, TuneTracker also unveiled several system-in-a-box products - which have Haiku and TuneTracker pre-installed.

Exactly twenty years ago, a document was published that played a huge role in establishing the web as we know it today. Twenty years later, and this simple and straightforward document is proof of an irrefutable fact: while closed technologies can change markets, open technologies can change the world.

Oh multitasking. That staple of computing that got thrown out the window with many modern smartphones. We got some rudimentary thing in its place - but even as multitasking on phone and tablets improves, its user-visible side remains cumbersome. Windows 8 has a neat implementation, and now it's time Android follows in it footsteps.

They're here! Whether that excites you or not remains to be seen, but the Galaxy S4, which will most likely become the best selling Android smartphone of the year by a huge margin, has been reviewed by all the major sites, and there's lots of interesting conclusions in there - although I think most of you will get the gist.

Nokia has posted its quarterly results for the first quarter of 2013, and just like the quarters that came before, there's not a whole lot of good news in there. The rise in Lumia sales still can't even dream of making up for the sales drop in Symbian phones, and when broken down in versions, the sales figures for Windows Phone 8 Lumias in particular are very disappointing. In North America, Nokia is getting slaughtered.More Features »
