The Android app market is a "chaotic cesspool", according to RIM. The makers of the BlackBerry PlayBook plan to limit the tablet so apps can only be downloaded from official channels, to avoid becoming like Android.
BlackBerry boss Alec Saunders claims that a quarter of Android apps are pirated and downloaded via dodgy channels. So he's confirmed that Research in Motion will restrict you to only downloading apps from the official BlackBerry App World.
The PlayBook will no longer be able to sideload apps from other sources when it gets its next software update, although app developers will be able to sideload to test their apps on the PlayBook.
The Android folk at Google pride themselves on the open and unrestricted nature of the Android app ecosystem. The Android Market, recently renamed Google Play, isn't the only source of apps for Android phones and tablets -- Amazon has its own app store, for example -- but even the official store is totally unregulated.
That lack of regulation is both Android's best feature and its worst. It's totally open so there's none of the restrictions found in the walled garden that is Apple's App Store, but there's also no guarantee of quality, or that apps are free of malware.
Google has also found itself in hot water over apps guilty of trademark infringement, a subject recently tackled by Manchester United.
Restrictions are nothing new to BlackBerry users, though. Heck, the PlayBook only just started doing email.
Is this a step towards a draconian walled garden, or is RIM right to protect its ecosystem? Sideload your thoughts in the comments or on our Facebook page.
