The ability to seamlessly transition between phone and tablet modes, coupled with the powerful processor and stunning display, aligns perfectly with my workflow and entertainment needs. I'm willing to invest in the premium experience and innovative technology offered by the Fold4. The superior camera system and faster charging are significant bonuses. While the price is high, the versatility and performance gains justify the cost for my specific needs.
