After months of being exclusively available at Dell.com and Best Buy, the Dell Streak can now be purchased at Amazon via AmazonWireless. The tablet's inclusion on the retailer's cell phone/service site is noteworthy because it now comes up in the results of a general "narrow by carrier" search, meaning it's finally been integrated into the AT&T population. It's the 42nd result out of 42 phones, mind you, but at least it now stands a chance of being discovered by people who don't know it exists.
The Streak is being sold for the standard $99.99 with new contract or contract extension (ignore that "AmazonWireless Instant Discount" nonsense) and $469.99 without a contract.
In related news, the Dell Streak 7 is also available at Amazon. It's not being sold with a service plan there, so a search for it on AmazonWireless returns no results. On the main site, though, it's in stock and ready to be shipped at no extra cost for $449.99.
T-Mobile sells it off-contract for $449.99 too, so I don't know where that $549.99 list price came from.[AmazonWireless (Streak) | Amazon (Streak 7)]
