Just in time for tomorrow’s Vista launch, Microsoft has updated its UMPC pages, which now bear a new "Windows Vista Ultra-Mobile PC" browser title. The old tagline, "Go Everywhere. Do Everything," has been replaced by the catchier, more accurate "Your Life. At the touch of your finger."
More importantly, particularly in light of my (and others‘) recent complaints about everything being called a UMPC, are the new hardware requirements, which include (as bullet-point number one) the Windows Vista Home Premium OS. Previous specs (cached here) listed Windows XP Tablet PC Edition 2005, which most handtops being called UMPCs did not have (hence my griping).
There are actually several editions of Vista, not just the one that "makes" a UMPC, but I’m not going to be a stickler . . . even though at this moment Asus, OQO, and Samsung (all listed as official UMPC manufacturers) don’t sell machines with Vista installed, Samsung and Asus actually recommend Vista Business, and Samsung doesn’t offer Vista upgrades.[OrigamiPortal]
