Family gathering in FL, some still with SS2 systems....

Just got back from FL where several family members arranged to meet for a few days and hoist a few. Of course the conversation eventually turned to SS, with two of us with SS3 systems and 3 with SS2.  Wouldn't be a family dinner out without a good friendly debate on the issue of upgrades, so I said I would post this topic in the community and see what SS has to say about this.  (BTW, those keeping count, there are more family members not in attendance with SS3 so we are not that far behind. :-)
