The Thrive is available in three Wi-Fi-only models—8GB ($429.99 direct), 16GB, and 32GB. These prices do not line up favorably with the most of the Honeycomb tablets we've seen so far. For instance, the Asus Eee Pad Transformer TF101 (3.5 stars) starts at $30 less, Toshiba PA3451U-1BRS Battery for twice the storage of the 8GB Thrive. And there's an $80 price difference between the Asus tablet and the Thrive when you compare 16GB models. Samsung plans to customize the OS down the road, which may slow down future Android updates. App selection is very weak. Even with a strong Wi-Fi signal, online video playback sputtered in our tests. Other Wi-Fi-only tablets are more expensive than the Eee Pad Transformer TF101, but still manage to best the Thrive. The Acer Iconia Tab A500 (3.5 stars), for instance, is roughly $20 more expensive than the 8GB Thrive—but you get 16GB for that price, and when comparing the 16GB models head-to-head, the Acer tablet is $30 less expensive. The Thrive does manage to undercut the price of the laptop batteries reigning tablet champion, the Apple iPad 2 , in both the 16GB and 32GB sizes, but with less-expensive Honeycomb options, it's not really a standout deal. In many ways the R850 looks like a supersized version of the R830 we'll be reviewing shortly. It has a similar black and chrome finish that looks very professional. Unlike the R830, however, it feels as though it's well bolted together and that it'll stand up to long-term abuse. For a 15-inch model, it's relatively thin at 25mm, and light too, tipping the scales at just 1.48kg. Under the bonnet the R850 has a fairly meaty specification. It uses an Intel Core i5-2410M processor that's clocked at 2.3GHz, but the chip's Turboboost technology allows it to automatically overclock itself to a maximum of 2.9GHz in short bursts when an application Toshiba PA3456U-1BRS Battery particularly needs it. The processor is helped along by 6GB of RAM and there's also a dedicated AMD Radeon HD 6450M graphics chip. Measuring approximately 6.9 by 10.1 by 0.3 inches, the Samsung Galaxy Tab 10.1 looks vastly different than every tablet we've seen thus far. Just kidding—they all look virtually identical. From the front, the Tab 10.1 most closely resembles the iPad 2 in overall Toshiba PA3475U-1BRS Battery appearance (no logos, just a black frame around the display) and the Motorola Xoom in shape. Like the Xoom, its 10.1-inch, 1280-by-800 pixel display makes it ideal for watching widescreen format video and HD content. Because Toshiba sees this laptop as primarily for work rather than play, it's kitted it out with a 15.6-inch matte display, as opposed to one that uses a glossy coating. The matte finish does mean that colours look a little less vibrant than they do on glossy screens, but this display's LED backlighting means it still looks very bright. Given the relatively high price of the laptop, we would have preferred to see a higher resolution than the 1,366x768 pixels on offer, especially as it would have made it easier to work on two documents side by side. By taking up more surface area than either the Xoom or iPad 2, the Tab 10.1 manages to be noticeably (not obviously) thinner and, at 19.9 ounces, lighter than either one. The plastic back panel is offered in white (like our review unit) or black, and both models are Toshiba PA3457U-1BRS Battery available in 16GB (as we tested) or 32GB capacities, the latter costing $599.99. An exclusive distribution deal with Best Buy will eventually fade into wider-spread availability this summer. The R850's 500GB hard drive offers plenty of room for storing documents and files and also has an impact sensor that can park the drive's heads, if it senses that the laptop is going into freefall,Toshiba Laptop Battery in order to protect your data. There's a DVD writer onboard too and you'll find a multi-format memory card reader tucked into the left-hand side of the chassis. This supports both standard SD cards as well as Sony's Memory Stick format.
