Just had a bag of Wotsits.
A number of observations:
1) The 'dust' on them isn't as fine. It's affected the overall texture of the snack, however it now means that it doesnt quite cling to your fingers at all, a cursory rub of finger and thumb and it's all gona.
2) They are ever-so-slightly more crunchy, and sort of hurt your teeth a bit more.
3) They are now baked, reducing the calorific content of a pack to 95kcal.
