What's the difference?
 

between the desktop models,

1)

and

2)

25% more power for the TI2
diiferent looks and less weight for the Ti2

Are you saying 1) is the TI2 and 2) is the TI?

And which is the current model? I was under the impression that they are both TI2s.

Picture 1 is TI1
Picture 2 is TI2

The TI2 is the current model of course

The TI2 looks much nicer imo.

Thanks guys, someone just tried to sell me Picture 1 as a TI2, I can't believe it and this is from a reputable store!
