Samsung’s out to conquer the mobile world with a handful of devices announced this week. The angle is price, with the Android-powered Conquer and Galaxy R, both mid-level devices offering broad consumer appeal. Also, Vizio is coming out with a new tablet, adding to the spray of iPad competitors to hit the market this year.

Samsung Conquer 4G (Sprint)

Price wins out as a winning feature with the Samsung Conquer 4G, marking Sprint’s first 4G-ready smartphone to launch on its WiMax network for under $100. Priced at an affordable $99.99, the Conquer 4G gets even cheaper after a $50 mail-in rebate. And while the price tag may be skimpy, Samsung’s latest mid-level smartphone packs a punch with some notable features. Powered by a 1GHz processor, with front and rear-facing cameras and a microSD slot to expand memory up to 32GB, this Gingerbread 2.3-powered phone offers a pretty good deal for the price. 4G is a major draw for buyers right now, and with Sprint being the only remaining carrier to offer true unlimited data, the Conquer is looking mighty fine.

Samsung Galaxy R

Extending its Galaxy series to the mid-level range, the Samsung Galaxy R is a step down from the upcoming Galaxy S2, though there’s still some redeeming qualities in this Android device. With NVIDIA’s dual-core Tegra 2 processor, the Galaxy R will still be a pretty powerful phone. It also comes with 1GB of RAM, a 5-megapixel rear-facing camera and support for shooting 720p HD video. The size of the Galaxy R itself is a tad smaller than the S2 at 4.19 inches, and it also sports a lower resolution display. But it’s still a feasible option for those looking to break away from feature phones without shelling out for the latest on the market. The Galaxy R won’t be available in the US before the S2 (to be released this month), though the North American release is expected soon. The price is expected to come in under $200.

Vizio Tablet

Price is also a selling point for Vizio’s latest Android device, simply called the Vizio Tablet. Looking to be a market leader amongst lower-priced devices, Vizio still wants to offer the best of features for this range. Priced at $299.99, the Vizio Tablet sports an 8-inch touchscreen with 1024×768 resolution, a front-facing camera, HDMI support, a microUSB port and 2GB of memory. Connectivity comes via Wi-Fi only, running a modified version of Android’s Gingerbread mobile OS. Vizio certainly isn’t ahead of the game, but it’s looking for consumer appreciation with integration for other Vizio devices. The tablet can be used as a universal remote for Vizio TVs, Blu-ray players, and even gadgets from other manufacturers. Look for the Vizio Tablet to launch this week at Sam’s Club, WalMart and Costco stores.
