Browser Performance
The Torch Mobile acquisition might imply that the PlayBook should have not only the most compatible browser on the market but also the highest performing one. Unfortunately that's not exactly the case. Despite having a comparable SoC to Apple's iPad 2 and something that should be faster than the Tegra 2 in the Motorola Xoom, the PlayBook (on average) performs more like an iPad 1/Xoom hybrid than an iPad 2 in our web page loading tests.
Let's start with the low level javascript execution performance tests: sunspider and BrowserMark.
Here's something interesting. The PlayBook actually does a lot worse running SunSpider 0.9 (something we keep around so you can compare our numbers to our older smartphone results) than running version 0.9.1. I'm not sure what's the root cause but here's a look at the iPad 2 vs. PlayBook under SunSpider 0.9.1:
In BrowserMark the PlayBook is about the speed of the original iPad with a single Cortex A8. To me this sounds like there's just a lot of optimization work that has to be done on the browser's javascript engine, something both Apple and Google have worked on extensively over the past year.
Actual timed web page loads (without Flash) look a bit better for the PlayBook. On average the PlayBook managed to load our test pages (stored local on our network) faster than an original iPad but slower than the Xoom, and no where near as quickly as the iPad 2. If you look at the performance breakdown, the PlayBook handles some web pages nearly as well as the iPad 2 and others render slower than on the original iPad.
Our tests really stress the hardware/software since the pages are delivered as quickly as possible without any network delays. Outside of our test environment I'd say the PlayBook experience does mirror the performance tests. Browsing isn't slow by any means, but it's not exactly iPad 2 quick.
RIM tells me that its intentions are to have industry leading browser performance and that there's a lot of room for optimization left on the PlayBook. I believe that there's a lot more that can be done here, the question is how quickly will RIM get around to doing it.

Did you have anything running in the background there? Gizmodo and Engadget both got within 10% of the iPad 2's score, the one here seems to be much slower.Anyways, as usual this is easily one of the best reviews.

This may be a sunspider 0.9 vs. 0.91 issue, RIM said the same thing but 0.9 for some reason gives us the scores you see on the PlayBook vs. the competition (just re-ran again to be sure).I'm still waiting for a response from RIM as to why the relative performance comparison is much worse under 0.9. We've stuck with 0.9 to maintain backwards compatibility with our older smartphone numbers but if need be I'll switch over to 0.91 for tablets.
I'm running 0.91 numbers now, let's see what I come up with.
Thanks for reading and your kind words :)
Take care,
Anand

This is definitely a 0.9.1 vs. 0.9.0 issue. I'm not sure what is causing the PlayBook to choke on 0.9.0. I will update the article with 0.9.1 numbers as well.Take care,

very high black levels on the screen is disappointing. (samoled/samoled+ is amazing)Also the bezel looks like its a huge percentage of the surface area, which is ugly.
7" seems to be the worst size, too big for pockets, too small for ideal consumption of entertainment or web.
The Base OS seems decent, although without email or calendar, we will have to give this another look in august.
That said, I still find tablets a niche device that few situations actually call for. Usually I find myself wanting a physical keyboard, or at least more screen space while typing. Also if you have to constantly hold it up, or buy a stand, why not use little laptops laptops, the screens don't need a stand : )
I find it a good device for a coffee table or any profession where you are standing/not at a table. Otherwise I'll stick to smartphone/laptop or desktop.

The contrast ratio is the same as the iPad 2, so the high black levels is an artifact of the high white levels. In other words, if you turned down the brightness to match the max brightness of the iPad 2, the black levels should be the same as on the iPad 2.Along the same lines, I'm wondering what was the brightness setting during the battery tests. Usually reviewers do something like set brightness to half during the battery tests. But that seems a bit unfair since the Playbook's screen is so much brighter than the competition's. Wouldn't a more fair comparison be to set its brightness output to be the same number of nits as the iPad 2 in its battery test? In effect, think of the screen as the same as the iPad 2, but with the option to really crank up the brightness if you're outdoors in sunlight.

So our old method was to set everything to 50%, but lately I've been doing brightness matching right around ~150 nits on these tablets.Take care,

Conclusion page:"I'm glad to see RIM experimenting with form factors. After using the Galaxy Tab 8.9 at CTIA I felt that may be the perfect balance between portability and functionality. The 7-inch PlayBook "
- something got mixed up there.

I wonder if the browser would be better if you had the option to hide the menu/address bar?Anand Lal Shimpi - Thursday, April 14, 2011 - link
You actually do have the option to hide the menu/address bar, it's in the upper right corner of the browser. That does improve things but it also makes it less convenient to navigate to the next website.Take care,
Anand

In the final words it would be worth reminding readers that it has no SD card slot, IMO a fundamental feature for phones/tablets nowdays.
