I was surprised when I saw the new Clie TG50 had been released, not because it's Sony's 3rd OS 5 device, but rather, because it seemed oddly familiar. After contemplating my deja vu, it hit me -- the TG50 looks like Sony's version of the Handspring Treo!
If you don't believe me, check out the graphic I've pieced together to make my case, showing how the similarity between the Treo 270 and Clie TG50. For instance, compare the styling on the lid hinge: both the Treo and the Clie use a smooth cone-shaped hinge corner cover that's strikingly similar. The two devices also both feature a built-in thumboard and no Graffiti area whatesoever (though one could install NewPen on either device for on-screen Graffiti capaility).
Even InfoSync seems to see the resemblance, mentioned in its news blurb announcing the Clie TG50. However, there are many differences between these two devices: the Sony runs OS 5, has a hi-res screen, Bluetooth and its thumbboard looks harder to use than the Treo's. Meanwhile, the Treo 270 is a PDA and GSM phone 'communicator' and is much smaller than the TG50. Still I see an interesting resemblance... don't you?
