I'd guess it's far more interesting from practical point of view than from pure theoretical.
1. Lower-than-Silverthorne power consumption, supposedly better performance and almost certainly less pain for programmer while extracting that performance.
2. Serious semico muscle behind it (assuming that TI is in and Samsung is coming).
3. All that during netbooks boom.

All these points together mean the first serious challenge to Intel/AMD dominance in general-purpose computing since MIPS-Compaq-Microsoft and IBM-Motorola-Apple alliances of early-mid 90s.
