Fierce tablet war is going on between IT providers, with various kinds of mobile device introduced by different developers. BlackBerry is going to introduce higher-end models that will support 4G connectivity in all the different flavors the various wireless carriers currently offer.

However, the release of Research in Motion’s BlackBerry PlayBook tablet was postponed by about one month from the original schedule, possibly due to the high customer demand for the iPad 2. According to DigiTimes, it is indicated that PlayBook shipments were delayed in software testing as well as shortage of touch panels as Apple already booked up most of the capacity available on the market place.

With cash reserves of $50 billion, Apple is capable of pre-ordering the components it needs for its popular devices, such as the iPad and iPhone lines. It is said that the IT giant have put down $3.9 billion to reserve a significant portion of the world’s touch screens in preparation for production of the new iPad. For companies hoping to compete with Apple’s iPad and iPad 2, this will be the latest round of bad news.
