BlackBerry PlayBook 16GB Tablet, $199

RIM's 7-inch BlackBerry PlayBook initially lacked a dedicated email client or support for Android apps, so it rated only 3 out of 5 stars in our review. Since then, however, RIM has announced an upgrade to the PlayBook OS that adds email, contacts, and calendar applications; an updated home screen; and support for Android apps. When the PlayBook launched, a 16GB version sold for $500. Prices have dropped since then, and now you can find the 7-inch tablet for only $199 at TigerDirect.com (with $4 shipping).
