If you've been impatiently waiting for that $380 WiFi-only Dell Streak 7 you pre-ordered, you can stop your fidgeting because it looks like Amazon, at least, has quietly started to ship them out to eager US customers -- the second market to get the Android tablet this week. Just to refresh your memories, it offers a dual-core 1GHz Tegra T20 processor, 16GB of storage, dual cameras, and, eventually, an upgrade to Android Honeycomb (3.0), something Samsung's 7-inch Galaxy Tab isn't guaranteed to get. But is that worth the Streak's higher price and shorter endurance? We'll let you and your wallet be the judge.
