I can't explain why your new camera seems slower compared to your old camera. According to test results I've seen, the HP tested slower at autofocus than the Canon. As for other issues, your HP had a bigger imaging sensor and fewer pixels. That alone is a benefit that current cameras can't match. I don't really have a recommendation. The differences between similarly priced cameras is not that large, so getting another similar to the SD1400 won't necessarily solve anything. MAYBE a camera like the SX120 IS or SX130 IS would have been a better choice for you... but maybe not.
