Last week saw a string of tablet updates as summer comes to a close, rounding out the widening range of Android devices that are becoming available on the market. This week, Lenovo adds to the Android tablet anticipation, as its ThinkPad is now available for pre-order. As schools re-open and expectations surround the eventual release of the iPhone 5, word of new Samsung and rumored Google phones promise an exciting season of smartphone grandeur.

Lenovo ThinkPad

Lenovo is targeting the business sector with its ThinkPad tablet, which was first announced back in July. With a launch set for this month, the ThinkPad is now up for pre-order, which can be done directly from Lenovo’s website. Sporting a 10.1-inch 1280×800 display, the Android tablet is powered by a 1GHz NVIDIA Tegra 2 processor, and boasts 1GB of RAM. The ThinkPad is Wi-Fi only, and comes with varying memory capacities at 16, 32 or 64GB. There are ports for mini-HDMI, USB 2.0 and micro USB. Prices range from $499 to $699. Just be sure to invest in a mobile hot spot.

Samsung Galaxy Precedent

Samsung has a pretty steady release schedule for Android devices, and the next smartphone to hit the market is the Galaxy Precedent. Though no exact launch date has been announced, WalMart is already taking reservations for the device, which will run on its TracFone-powered mobile virtual network operator, StraightTalk. The true perk of the Samsung Precedent is its price point: it costs only $150 without a contract. Paired with StraightTalk’s unlimited voice, text and data plan for $45 a month, Android has found a way to the masses. So what about the Precedent’s specs? They’re decent, with an 800MHz processor, 384MB of RAM, a 3.2-inch display and a 2-megapixel camera. Running Android 2.2 Froyo, the Precedent comes with Wi-Fi, GPS and Bluetooth support, making it a steal for the mid-range price point.

Nexus Prime

The next Nexus phone from Google is just as anticipated as Apple’s upcoming iPhone 5, with both expected to hit the market in October. What a showdown that could be. The latest rumors surrounding the Nexus Prime indicate that the device will run Android Ice Cream Sandwich, which merges Google’s smartphone and tablet operating systems into a single version of the software. As far as hardware goes, we’re on the lookout for a 1.5GHz dual-core processor, with a 4.5-inch display featuring 1280×720 resolution. While rumors run wild in the smartphone sector these days, Google has hinted at a new Nexus phone for the holiday season. We’ll just have to wait this one out like good little boys and girls.
