In introducing its new $2000 Aura cell phone today, Motorola repeated comparisons to luxury watches. So contrasting it to an iPhone or a BlackBerry or even the Prada phone may not do it justice. How about facing it off against one of the most famous mobile status symbols of them all, Rolex’s eternally popular Oyster Perpetual Submariner? I did just that for this T-Grid, and found that it’s a close contest–the two gadgets have much in common, but both sport some attractive features that the other doesn’t. Bottom line: If you’ve got a spare $8K, you might want them both!
