I have Android 2.2 on my Dell Streak 5. It is rock solid and I’m NOT locked into a proprietary application like iTunes. The Streak 5 is perfect for travel, movies and light internet use.
I think 7” is a sweet spot for handheld tablets. We have an iPad as well and it is a 2 handed operation. I may get the Streak 7 this summer.
Don’t know anything about the Dell model, but sure do like the Tab.
I hate iTunes - a major pain in the A??.
