Tablet devices are clearly ruling the roost at the Consumer Electronics Show at Las Vegas, with a wide array of companies – including Motorola, Dell, Asus, Acer, LG, Vizio, Toshiba, Samsung, NEC and others – using the platform to announce their respective tablets, mostly Android-powered ones.

Among the tablets that were announced at the CES – most of which do not have appear to be anywhere close to becoming a serious iPad challenger - included the Android 3.0-powered ‘G Slate’ from LG. The company did not disclose much detail about the device, other than saying that it is compatible with T-Mobile's HSPA+ 4G network.

Another tablet, the ‘Streak 7’ from Dell, is a 7-inch tablet device, which may not appeal to many customers due to the reason that it runs the Android OS 2.2 version, which has not been optimized for tablets.

The other tablets at the CES included the Android 2.2-powered Samsung Galaxy Tab, which has only been refreshed for Verizon Wireless with LTE; and a horde of 7- and 10-inch models that either run Android version 2.2 or 3.0. The specs of most of these tablets appear rather lackluster, and none of them appear to be revolutionary in terms of either features or functionality.

By far, the best tablet to be introduced at the CES is the 10.1-inch Motorola Xoom. According to Motorola, the 3G tablet – to be backed by Verizon Wireless – will get a 4G update later this year.
