The 2 links (long ones) below are the specs pages for these 2 cameras.
My girlfriend was just at Best Buy deciding between these 2. They told us wrong info about the lens and the battery for these. They are not all that bright at Best Buy.
The only differences I could find with these are
1. Small size difference.
2. Weight difference of 5 grams
3. W1 has SLIGHTLY better flash range
4. W1 has bigger screen
5. W1 uses AA rechargeables and 100 uses Lithium.
Everyone wants to say lithium is better but in this case, theres a
whopping 20 picture difference in charge time and I think a 10 minute
difference in playback time bet. the 2 cameras. To me that means
Its just about cost of spare batteries (Costco sells 6 good rechargeables
for 20 bucks).
6. I think the 100 has a couple more scene modes
Thats about it for these. Otherwise they are the same. Look at the specs.
She bought the W1 opting for the larger screen.
If I didnt answer a specific question of yours, its cause I dont know the answer.
