Blackberry is expecting the release of its tablet, the PlayBook, to take the business world by storm in a similar fashion to the way its mobiles did.

The operating system is geared towards the business man’s needs and BlackBerry will hope they can lay claim to the commerce position in the tablet market. However, with a new array of nifty Android tablets, can the BlackBerry PlayBook carve out its niche?

On first appearance the BlackBerry PlayBook is a solid 7 inches tablet. Most of the current generation of slates have 10 inch screens, which though larger, are not as portable – but do offer greater visual clarity due to larger size.

Weight wise the BlackBerry PlayBook is 0.9 lbs compared to the Galaxy and the Motorola Xoom which weigh 1.32 lbs and 1.6 lbs respectively. Though, as far as dimensions go, it really is a case of portability versus screen size.

The screens themselves are also varied technology wise – the BlackBerry PlayBook has a 7-inch screen running at 1024×600, which for its smaller screen size does a more than adequate job.

Both the Motorola Xoom and Samsung Galaxy 10.1 run 1280 x 800 resolutions and so offer more clarity and a better quality image because of their larger face size and pixel count. It must be said that the Motorola’s HDMI port gives it the edge for video play.

The PlayBook is powered by an ARM Cortex A9 1GHz dual core processor, a more than capable chip for the little BlackBerry. The Xoom and Galaxy use NVIDIA Tegra 2 dual core 1GHz chips which have excellent multitasking abilities and with both of the aforementioned running Android 3.0, the PlayBook needs to be something special and fortunately its ARM chip is up to task.

The BlackBerry PlayBook relies on QNX Neutrino based operating system, a new and said to be innovative OS for the business classes. The Android tablets use the new Honeycomb OS which is tried and tested and it perhaps has the upper hand for this reason alone.

Camera wise the Samsung uses an industry leading 8MP camera, offering 1080p recording, whereas both the BlackBerry and the Motorola use 5MP cameras at the back that offer 720p recording capabilities.

At the front of the slates, the Motorola and the Samsung have 2MP cameras but the BlackBerry has a 3MP camera, making it the choice for face to face calling.

Connectivity is a bit of an issue for the BlackBerry PlayBook, as it will only offer Wi-Fi connection initially, though 3/4G connections are said to be in the pipeline.

The Android 3.0 machines are better equipped for connectivity, specifically the Xoom, which is very strong in this area – offering Bluetooth, USB and HDMI. The BlackBerry does allow synching with its model of phones and supports Flash.

We know that the Android devices are well capable of touching the 10 hour mark with their battery, but aren’t so sure of the BlackBerry PlayBook’s capabilities yet.

We can only guess that if BlackBerry is as good at squeezing the power from its phone devices as it is from its PlayBook, it will have no problem hitting in or around the same as the Android machines with its tablet device.

Application-wise the Android 3.0 machines are better equipped than the BlackBerry, with its new OS. Android 3.0 has seen a lot of support application-wise and is superior in this part of the battle.

Though BlackBerry PlayBook will probably suggest the more serious business user will not have the same interest in applications that the consumer orientated tablet user will.

Looking at the two types of slates, it’s apparent that they’re aimed at two different markets. Though, for the average user, which most tablet purchasers are, it does make more sense to buy an Android 3.0 slate.

The BlackBerry has a smaller screen and less functionality making it less desirable for the average user. It may be better for the business user who has different demands, met more than likely by its new BlackBerry OS.

In December last year, I received an email from the Google Adsense team informing me of a webpage within MrDefinite.com that had violated Adsense policy. I was given 3 working days to make changes to the content.

On the same day I quickly disabled the webpage mentioned from being viewed publicly and sent a policy violation appeal to Google to reconsider re-enabling ad serving on the site.

To ensure that MrDefinite.com complies with Adsense policy, I even spent a couple of hours amending and censoring through entries to ensure the site is a “clean” one and to avoid similar problems in the very near future.

On the following day, I was sent the following message telling me that ad serving would be re-enabled within 42 hours:

The ads appeared shortly, but it wasn’t until a couple of days later during the first week of the new year that it was disabled again.

Not knowing what happened, I requested for a policy notification to be re-sent. To my surprise, it was the very same notification as I mentioned earlier.

I wrote to Google Adsense to clarify that I had already made changes to the webpage involved and sought their help to look into this matter. Again I was sent an email telling me ad serving will be re-enabled within 42 hours.

Today marks the third day and still no ads have been served yet. I have sent an email to inform Adsense of such a complication and hopefully they could give me a feedback on this and investigate into the issue soonest possible.

Anyone experienced such a problem before and mind to share?

Update: Adsense has been re-enabled!
