I'm afraid that fence sitters will only get splinters this time (as in an opening day sellout with deliveries sliding to June/July).
I don't buy the negative press and vocal naysayers who are underwhelmed with the Apple Watch. This one is going to sell better than any Gen 1 Apple device on the (1) design (puts all other smartwatches to shame), and (2) notifications/replies, regardless what cool software is down the line. So many people get tired of dragging out phones (pockets, purse, backpack, across the room) to check a mail/message/call. This ability to triage communications on a good looking watch is going to bring in the herd of buyers. All the other stuff it can (or will be able) to do is just gravy.
