The 10mm-thin Dell Streak runs a customized Android 1.6 Cupcake UI. No worries though, Dell should deliver a v2.2 Froyo update later this year for a serious speed boost. Still, the Snapdragon processor should be fast enough even at Android 1.6, though the 256MB RAM seems a bit low, some smartphones have double that amount.

Photos of the Dell Streak phone/tablet thing

The screen on the Streak is a 5-inch TFT with WVGA resolution (800 x 480) with multi-touch support. The sheer size is definitely an edge in web browsing versus phones and it also has a built-in GPS receiver with Google Maps.

Other features include a 5MP auto-focus camera with dual-LED flash and a secondary camera for video calling (take that iPad). The retail package also comes with a dock with HDMI out.

Watch Kevin Andrew from Dell talk about the Dell Streak and give you a quick video demo. First he calls it a tablet, then he goes on to say he’s used it as a primary phone. Gosh, this thing weighs 220 grams so that really shows some dedication. Kevin naturally admits he’s used a Bluetooth headset to do most of the talking on the Streak.

The Dell Streak will be available exclusively on O2 UK starting on 4 June but pricing info hasn’t been announced yet. It should be available from O2 stores and also Carphone Warehouse and Dell online stores.
