I suspect that stats will have a lower impact on play, but will instead serve as the gateways to perks.
The SPECIAL chart in the garage seemed to associate ten perks with each SPECIAL stat, one for each value. Assuming that that chart indicates what SPECIAL values are required to choose a particular perk, and assuming the best perks are the ones associated with high values, then part of leveling and character development will be raising SPECIAL in order to qualify for desired perks.
It probably won't hurt you to have a 1 in a stat, aside from the fact that you won't qualify for any associated perk that requires 2 or more.
INITIAL stat choices should NOT be overly important. We don't want to have to abort our initial characters several times while we figure out the game, or do extensive wiki research before we create our characters. Our characters should be pretty flexible at early levels, with the important choices taking place as we level. We shouldn't be able to master everything, but we should have enough flexibility to master anything we want after we figure out how the game works.
The choices that matter should be what to do with perk picks as we level, not how we allocate those initial starting stats.
