The Surface 2 and the Lumina 2520 will probably be the last true RT device, if the rumors of Threshold holdout to be correct, it won't matter as the Small Screen SKU will over screens 3.7" to 9" running ARM or ATOM, will not include a desktop and most likely include Office Gemini, so a single SKU will cover phones and lower power tablets.... no drama, no backtracking....We shall see... I wouldn't take the chance that the patient will still be around to receive that late in coming breath. ;-)
