Dell has a competitive lineup of mobile devices brewing, as we found out with the Thunder and Looking Glass leaks last week. To start off this week, Android Central has unveiled two additional devices – Sparta and Athens – that will have Android at their heart.

Both devices fall under the 11-inch category on Dell’s roadmap. Sparta is defined as a netbook tablet, while Athens will be a true netbook. The difference between the two should be obvious at this point. They have an ARM processor, optional 3G, WiFi and Bluetooth. The specs are vague, and hardly interesting, but it’s better than nothing at this point.

Dell LG Pro is another device that looks to be a HD screen and digital TV. An iPad competitor perhaps?
