I thought the $800 price of the XPERIA X1 was high, but according to Engadget the Sprint Treo Pro is priced right now at US$699.99 over on Best Buy. I'm not sure if this is the real final price though since online stores like Best Buy and Amazon have been known post high prices before availability. The SIM unlocked Treo Pro sells from Palm for US$549 so this price makes little sense.
We earlier reported that you could pick up a Sprint Treo Pro, but it seems that Sprint jumped the gun by posting the page and we won't see the Treo Pro until sometime in February. I find the Treo Pro to be one of my most useful and stable devices, but $700 is too steep for that device.
