- Poor netiquette to not post a link to the actual article:
BlackBerry PlayBook 4G LTE hands-on -- Engadget
I find this quote interesting:
"It's good news for those who aren't fans of carrier bloatware slipping into their tablets, although it also means there's no Bridge-free BlackBerry Messenger or built-in turn-by-turn navigation. We're also baffled by the lack of built-in hotspot creation support, which would make a very convincing case for the PlayBook as an oversized router."
Wow. Really RIM?
How can they not include BBM on this thing? That's just ridiculous.08-10-12 09:00 AMLike 0 - Yeah, except QNX process switches are faster than Unix thread switches. It's been stated before, the cost of context switching in a QNX kernel is minimal.

Plus, let's get back to the playbook. Unless I'm mistaking, the playbook browser is built on adobe air. That's yet another layer for hardware calls to traverse. I stand by my statement that the performance gains are not only related to the bump in clock speed, but also to enhancements to the browser rendering engine.08-10-12 09:34 AMLike 0 - It doesn't matter. The fact still remains, the average system call on another unix system requires 2 context switches. On a microkernel system, the number of switches is exponentially higher. QNX context switches may be fast, but they still take time. Exponentially increasing that time makes the system slower.

If you're going to throw out claims about the exponentially time increase required to perform tasks on the kernel, how about some evidence? Why aren't the benchmarks demonstrating the system to be as slow as molasses compared to the competition?08-10-12 09:57 AMLike 0 - This review is weird. They sing the praises of the 4G LTE PlayBook (for the most part) throughout the review, then at the end they say it isn't any good and you should buy something else. They just couldn't overcome their intrinsic dislike of all things RIM. Still, any positive words about a BB product from Engadget is progress, I suppose.beavertail2 likes this.08-10-12 10:05 AMLike 1
- sleepngbearRetired ModeratorThe new PB is faster than the old one, that's the bottom line. Does it really matter at this point how efficient the microkernel architecture is or isn't?!08-10-12 10:32 AMLike 2
- Here's another positive article, perhaps a little too positive, but it's a nice read.. It doesn't seem to merit a new thread, so I'm going to add it to the discussion here. Hope that's OK

And it had better be a part of reviews or you are going to end up with more threads on here with people being told 'why did you buy it if it didn't fit your needs then' lol.Last edited by torndownunit; 08-10-12 at 11:29 AM.

It's a great piece of hardware that needs more apps. If you are reviewing it comparing side by side with other tablets, based on what people normally use tablets for, it's hard not to come to that conclusion. RIM is not going to change the entire consumer bases mindset about what a tablet should be used for. And people want to be able to use their apps. That is always going to be a key part of any review.

The other issue he mentions is another issue commonly brought up on this forum. If you own a Playbook 1, is the Playbook 2 worth upgrading to at it's price point?
They are both very fair points, raised in many threads about the 4G Playbook on this forum. Both would be valid reasons for not suggesting people 'jump on it'.08-10-12 12:36 PMLike 0 - i think when they bring in the price factor its a no buy. remember this is more than $500 again or you are locked into a 3 year data contract and you can buy a wifi version for under $200 that will do mostly the exact same thing. Its hard to recommend he 4G version unless you have certain specific needs or criteria08-10-12 12:37 PMLike 0

That leaves the only real advantages being (i) convenience (easier not to have to have one of the MiFi things with you) and (ii) the faster processor (which according to the reviews, is a noticeable improvement)jpash549 likes this.08-10-12 12:46 PMLike 1 - why is this a shock RIM has stated numerous times that BBM was coming to a QNX based system until BB10 is released. At the very least Engadget should know this or do a little research before posting their outrage that it is not there.

FYI, the 'outrage' from Engadget wasn't about the lack of BBM. It was about the lack of any mobile hotspot feature. This is STANDARD on any other tablet out there, FYI.08-10-12 03:22 PMLike 0 - It doesn't matter. The fact still remains, the average system call on another unix system requires 2 context switches.

I'm not saying the thing is DOA, but $200 off is not much for a 3 year contract.
We'll have to see what the US does in terms of pricing and contract terms.08-10-12 04:01 PMLike 0 - The review was overall positive, but the pricing is a huge negative. $350 for a 3 year contract is awful, especially since you're stuck with a 32 GB tablet for 3 years, which (A) is not a lot of storage space for those who download big apps, and (B) will likely not be able to smoothly run the latest apps after a couple of years.

To reverse a question asked earlier, if the microkernel is SO good, why is RIM the only company attempting to use it in mass produced consumer goods?08-10-12 09:46 PMLike 0 -
