Here's the latest leak on mobile devices. Engadget has all the information on Dell's new Windows Phone 7 and Android devices. It's the Dell Lightning which runs on Windows Phone 7 OS and the Dell Thunder which runs on Google's Android operating system.

Dell Lightning:
The renders on these slides look slick as hell, but they're no match for the spec sheet, which looks even better: 1GHz QSD8250 Snapdragon processor, WVGA 4.1-inch OLED display, AT&T and T-Mobile 3G, five megapixel autofocus camera, 1GB of flash with 512MB RAM plus 8GB of storage on a MicroSD card (non-user-replaceable, we're assuming), GPS, accelerometer, compass, FM radio, and full Flash support including video playback.

Dell Thunder:

According to Engadget, Lightning is Dell's answer to Windows Phone extravagance. Thunder runs on Android 2.1 and has a 4.1-inch WVGA OLED screen.
There's a heavily custom Dell "Stage" UI on top, which seems much different (and classier) than what we've seen on the Streak or Aero. It apparently ties into Facebook and Twitter for social networking, and taps Swype for a touchscreen keyboard replacement, along with grabbing just a pinch of HTC's Sense good looks. Dell's document also claims this has Flash 10.1 for watching web videos, along with a mention of an "integrated web video Hulu app." We're not sure how that works, but hopefully it's everything we ever dreamed mobile Hulu could be. Under the hood we'd guess there's the same Snapdragon chip that's powering the Lightning, but we don't have specific specs. There is supposed to be an 8 megapixel camera, however, and the phone will be sold in AT&T and world-friendly HSDPA versions around Q4 of this year, with an LTE model to follow near the end of 2011.
