HP Slate 7 The HP Slate 7 shapes up pretty well with its spec. It boasts an ARM Dual Core Cortex-A9 1.6 GHz processor, 1GB RAM and comes with 8GB of internal storage. Importantly the Slate 7 comes with a microSD slot which can expand the memory by up to 32GB, so this makes up for the slightly small storage spec.
While there is a bit of a big gap between where the screen finishes and the edge of the tablet, the overall design of the Slate 7 is pretty good. It sports a nice stainless steel frame, and the device we saw had a metallic grey looking finish to the back (it’s also available in red), the result is an aesthetically impressive tablet. It weighs a pretty reasonable 370g and measures in at 197.1 x 116.1 x 10.7 mm.
The 7-inch screen (which as mentioned above, doesn’t come anywhere close to the edge of the tablet) isn't going to dazzle you at all. But that’s not what you expect from a cheap entry-level device. It has a screen res of 600 x 1024 pixels, and a pixel density of 170ppi, this lags someway behind its two main rivals the Nexus 4 and Kindle Fire HD, which both have a pixel densities of 216ppi. It didn’t look that bad in real life though, to be fair to the Slate 7. Price;$169.00
VS BlackBerry PlayBook The BlackBerry PlayBook is certainly a more refined tablet now that it has its OS 2.0 update, but it only really worked to bring the tablet closer to the standards of its rivals, rather than offering something you can't get elsewhere.RIM's BlackBerry PlayBook is a fast, powerful 7-inch tablet with HDMI output, advanced multitasking and security, and a browser that integrates Adobe Flash 10.2 for a desktop-style Web experience.
But, The 7-inch screen cramps the powerful browser; the wake button is difficult to push; and app selection trails the competition.
The bottom line: The BlackBerry PlayBook ably showcases RIM's powerful new mobile operating system, but its middling size diminishes many of its best features. Specifications

But, Android still needs more tablet-optimized apps, newer games have frame rate issues, and HSPA+ speeds seem particularly location-dependent.
The bottom line: With its excellent design, useful software features, and low starting price, the Nexus 7 is the cheapest way to experience the best that the Android OS has to offer. Specifications
