Thanks. I did see that it was more then just a quick pop-in for the CPU. I also noted that for the most part people don't seem to think that they give a whole lot of performance increase over an i5. Ten to 15% isn't really worth the effort to me, and I probably wouldn't even be able to tell during usage. Ram and SSD would probably be the extent of my hot-rodding. I'm still flopping around, but now, after convincing myself that I don't care about the larger resolution, I've added the Q704 to the list. There isn't much discussion on these, beyond some fan issues which seem to have been resolved (I think), but the specs put it in between the T734 and T904. It can't handle as much RAM (8G max) and I'm not in love with the hybrid nature (in fact, I think I hate it), but it's got higher resolution and they can be had relatively cheaply. My oh my! Just buy something already!
