I agree with everyone else. Kinda hard to point you in the right direction without knowing why you feel the need to upgrade.
Only thing I can add here is some food for thought:
Point-n-Shoot:Goods
1. Small and light.
2. Mostly automatic, can be good if you don't know how to create correct manual exposures.
3. Usually has a very good focal range without requiring multiple heavy lenses.
4. Smaller initial cash outlay.
5. Easy to learn.
Point-n-Shoot:Bads
1. Can be tricky or impossible to get good low light/night shots/fireworks.
2. Usually pretty noisy at high ISO settings for low light/night shots.
3. Shutter lag can be a problem.
4. Difficult or impossible to use manual exposure settings if desired.
DSLR:Goods
1. Usually very good performance in low light.
2. Large selection of high quality lenses available.
3. Can use larger/stronger flash units for more distant subjects.
4. Very little(imperceptible???) shutter lag.
5. Battery usually lasts longer since LCD screen is not on as much.
6. Easy to use manual exposure controls(actually preferred more by me).
7. Usually has larger imaging sensor than point-n-shoots.
DSLR:Bads
1. Heavier
2. More expensive initial outlay. Even worse once you get hooked on quality glass.
3. Vulnerable to dust on sensor(unless you get one of the new self-cleaning cameras) or back of lens.
4. Bulkier. Usually need to carry your gear in a bag.
5. More conspicuous in sensitive situations(concerts/pro sporting events etc.)
6. Get caught up in petty brand flame wars on photography forums
7. You feel much worse if you drop a DSLR and expensive lens.
Hope this helps for now.
