I would think this question would be better asked in the Gear General section but,
Yes, stock it is expensive crap. Null makes it amazing!
The bottom line is buy old Galaxy Gear for cheap or buy new Gear 2.... and that really depends on your $$$ and if Tizen is as unrestrictive as they are claiming it will be. So either way your good but rooting it is a must, and getting Null on it is key.
