To me, its like a notebook vs. elementary writing practice sheets. But maybe thats just me. The journal on the Pocket eDGe is fine, works well, just go thru more sheets than on the full-sized version. For me, a lot more... proportionally more than the difference in area. Given that I'm not cutting down trees to do so, it's not a deal-breaker, but I admittedly like to write smaller and finer than I can on the Pocket eDGe.
Ya....good guess!!!! And I look forward to hearing about the hub. It should be no problem at all.
