One of the easiest ways to differentiate between the BlackBerry Playbook and Samsung Galaxy S Tablet is by comparing their size. Here, you might probably consider going for the Samsung Galaxy S tablet because it comes in different size models. For instance, the Samsung Galaxy S tablet comes in different versions, such as a 7-inch, 7.7-inch, and 10.1-inch versions.
In contrast, BlackBerry Playbook comes only in the 7-inch version. Since Samsung Galaxy S tablet comes in different size models, you have the option of picking whichever size you want. Another obvious difference between Samsung Galaxy S tablet and BlackBerry Playbook is that the former uses the Android Operating system while the latter uses Blackberry Tablet OS.
In terms of cellular connectivity, the Samsung Galaxy S tablet takes the lead as it is equipped with a cellular modem that allows it to connect to the internet, whereas BlackBerry Playbook does not come with a cellular modem though it is equipped with WiFi.
