No. The feature set can only go as far as the architecture will allow. It's not that it can't multitask, it can and quite ably. What it can't do is evolve past a certain point.

Disadvantages in the microkernel exist however. A few examples are:
•Larger running memory footprint
•More software for interfacing is required, there is a potential for performance loss (note, the QNX system is extraordinarily fast).
•Messaging bugs can be harder to fix due to the longer trip they have to take versus the one off copy in a monolithic kernel.
•Process management in general can be very complicated.
Sounds like how the BB OS is now.... hope QNX doesn't have these issues when they launch on phones.

Sound like you have discovered an issue that RIM didn't discover.

The Mac actually uses a hybrid Micro/monolithic kernel and I don't think the performance will be any problem judging by the Playbook.

But having said that, they can over time fix this by making the kernel more of a hybrid like that what NeXT/Apple have done.

When it works, it's great, but it's unpredictable and I have very few apps loaded and don't really multi-task - i.e. very few apps open at the same time. The Wifi goes in and out CONSTANTLY, no matter where I travel, so there have been times that I've wanted to throw it out the window. It seems I've done a lot of hoping with Rimm and I'm a loyalist. The benchmark that I use for any device OEM is Apple. Apple stuff just works, isn't buggy, doesn't crash, etc. It just works. If Rimm were to make up ground in this area with their nextgen devices, it's a game-changer in my eyes.
Now back to microkernals...So these new BB10 devices will be based on QNX, correct? If I understand the OP, this suggests I may be disappointed?
Thanks

QNX is built around scalability and distributed networking.
The issues regarding performance hits discusses in the OP largely refer to IPC, which was why Mach ended up as a hybrid kernel rather than a micro in OS X. The research hadn't been completed yet.
Look up the L4 family of microkernels. QNX built their IPC system off of this research foundation. In a nutshell, they succeeded where Apple and Mach gave up, then patented their results.

What do I go to school for to understand microkernals n such things?
