Generally, some of the advantages of the Olympus Tough-3000 compared to entry-level DSLR competitors include: it records lower quality movies (720p @ 30fps vs none), has image stabilization (sensor shift vs none), is newer (january, 2010 vs august, 2006), is much smaller (compact 95x65x23 mm vs prosumer size 129x98x62 mm) and is slightly less expensive ($187.99 vs $547.72).
However, on average it has a much smaller sensor (1/2.3" 6.1x4.6mm vs APS-C 22.2x14.8mm), doesn't have a viewfinder (none vs pentamirror), users slower contrast detection autofocus (contrast detection vs phase detection), doesn't shoot RAW and has a built-in lens.
