    Did I say it was a magic bullet? No.

    I simply said that RIM can copy other people easily because QNX is a standard certified OS that is designed to be commercial off the shelf. It is supposed to absorb like a sponge --- easy to port stuff to the OS.

    I simply said that other mobile OS'es can't easily copy what the Playbook has --- because doing so would require them to yank out their existing kernels and put in RTOS kernels. Is it useful in real life to have an HD video playing in the background? Not really --- limited to situations like doing a sales presentation with the Playbook hooked up to a big tv and you are looking at the presentation notes on your small Playbook screen.

    But does RIM having a full feature RTOS have an big effect on the mobile landscape in the future? Yes. It is going to cost RIM less to make their handsets in the future.

    Go and take a look at the iphone teardowns --- they use the A4 CPU for the higher level OS and they use a separate baseband chip for the cellular radio. The baseband chip has its own dedicated RAM and ROM chips that Apple has to pay for and has its own RTOS (ThreadX RTOS) that Apple has to pay licensing fee for. Apple can afford to pay extra money for these things --- because Apple gets their LCD screen and flash memory at much cheaper price than the rest of the industry.

    Go and take a look at the android phone teardowns --- they mostly use Qualcomm integrated CPU/Baseband chip to save money. But in order to do that --- they ended up with using 3 operating systems on a Quadroid phone. Most Quadroid phone runs OKL4 hypervisor OS at the bottom. Then 2 "guest" OS sits on top of the hypervisor --- Qualcomm's RTOS which runs the baseband function and Android OS which runs all the higher level stuff. Go to OKL4's websites and their white papers will say that it takes about 5-7% performance hit for having a hypervisor.

    Future QNX-based Blackberries will run just a single operating system --- with integrated CPU/Baseband chip for cost savings and without having performance hit by the presence of a hypervisor.

    This isn't about the hardware or the underlying OS dude, this is about the GUI, the fact that the Playbook uses cards and card gestures which are practically identical to webOS. Just what did you think I was talking about?

    There is no use of arguing as RIM ******* will never acknowledge that Playbook is a blatant rip off of WebOS.

    Yeah future blackberries will be sold by Microsoft or Dell as by that time RIM will be bankrupt and will be brought by Microsoft or Dell.
    Man let us talk about the present that would be more interesting and then keep ranting about the future.

    If you are talking about UI, then you shouldn't worry about Playbook's current UI --- you should be worrying about what TAT is going to do with the Playbook, which TAT is replacing it bit by bit.

    There are only limited things QNX can do with the Playbook UI --- they are not GUI specialists and they use Flash to make the Playbook UI. Flash can't do 3D stuff, so the Playbook UI is limited to 2D only.

    You should be worrying about what kind of 3D UI TAT is going to put on the Playbook.

    Interesting read.
    That and HP probably realizes it's a waste of time and money to drag themselves though the mud sueing over something that's esencially a generic concept.

    You should be worrying about whether the current HP CEO really cares about the Palm acquisition, whether he has the patience to wait for solid results and whether he is going to finally listen to Wall Street and transform HP into an IBM clone.

    The Palm acquisition was a Mark Hurd idea --- he is gone. The current CEO came from SAP and he is a lot more familiar to things like the HP's 2008 $13.9 billion acquisition of EDS. A couple of bad launches, and you could see the current HP CEO jettisoning Palm like Cisco jettisoning Flip --- simply because it was not his idea to acquire Palm in the first place.

    You think that HP is going to care about a lowly $1.2 billion Palm acquisition when they are always hunting to buy $10-20 billion consulting businesses.

    You should stop talking about the future and start talking about the present.
    Last I heard Blackberry touch 9xx whatever was going to be delayed by 2 months and going to release in august.

    RIM stocks have tumbled below 50$ for the first time in 6months and analyst are predicting to be at 35$ in 6 months.

    Btw HP is going to put WebOS in all 100million PC they sell every year so the future of WebOS is looking brighter day by day while RIM is looking dimmer by the second.

    Your beloved RIM will be purchased sooner rather than Later by some big company, may be google will buy them just to control the whole thing and finally make Skynet.
    Btw atleast HP CEO has the sense to talk to journalist unlike RIM CEO, who can't even complete a normal interview with BBC journalist.

    You are talking about the same HP CEO that went into hiding. At least the RIM CEO showed up for an interview.
