Don't take this as the gospel, but online retailer Expansys has gone ahead and listed Dell's Venue Pro -- affectionately known as "the Windows Phone 7 device with a portrait QWERTY slider" -- with pricing and availability date in tow. Which, if you're wondering, is £499.99 (or about $783 in US dollars, when crudely converted) and Monday, November 8th, respectively. That's just over two weeks away, which means if it is true, you won't have long to wait... and if it's not true, you'll know soon enough, anyway.
Update:PC World'sspotted the same date and price for the Venue Pro on Amazon UK. You lucky Brits.
