Should i buy the dell streak 7 I know the specifications are quite good but I am worried about the fact that its still only running 2.2 froyo and that the screen resolution is not great . Would i be able to update to 3.0 without ruining my device and also does anyone know if the low screen resolution affects the experience that much. If streaks not good should what other tablet should i buy note that my price range is around the streaks ie. 300 pounds or 400 dollars. Thanks.
