The Dell Streak 7 when launched, was one of the first tablets to feature an NVIDIA Tegra 2 dual core processor but, had a relatively low resolution of 800 x 480 compared to other tablets on the market and came with Android 2.2, while other tablets on the market were coming with Android Honeycomb. Since it's release, Dell have updated it to Android 3.2 Honeycomb but, by unofficial means, the tablet had Android 4.0 ported to it.
The Dell Streak 7 is now discountiuned and as it didn't receive Android 4.0 officially, it's very unlikely to receive an update to Android Jelly Bean through official means. Fortunately, developers over at TabletROMs have ported Android 4.1 to the Streak 7. CyanogenMod10 updates the Dell Streak 7 tablet to Android 4.1, gives the tablet a faster interface, improved search and a better keyboard. CyanogenMod10 also brings Google's Answer to Siri which, when you ask the tablet questions it speaks the answer out loud to you.
