With the Treo 650 about to make its way on the shelves, the current model, the Treo 600, is now available at Amazon for $199 with rebates ($200 from Amazon, and $100 from AT&T when you activate a Mobile Internet plan valued at $19.99 or more). Though the AT&T rebate is good for purchases through September 16th, the Amazon rebate is only good for another two days (must be purchased by August 25th).
