Noah called it - as of today, the S60 QWERTY Nokia E75 is available from the company's website, and will be available (we presume, at least) in Nokia's company-owned stores shortly. Offering a 3.2 megapixel camera, a-GPS, microSD card slot, and a 2.4-inch QVGA (320x240) display, the device seems to be a great compliment to the Nokia E71. Furthermore, the phone is the first to use Nokia's new E-Mail solution, allowing personal users to set up their accounts. In the US, the device will work on AT&T's 3G service, whereas T-Mobile users will be able to use it on EDGE only (due to varying 3G frequencies).
As a side note, I am not a big Nokia fan (never preferred the OS), however I have been very impressed by both this device and the Nokia E71. Check out Noah's review of the Nokia E75, as he points out some pros and cons that may be crucial when it comes to purchase time.
