Generally, some of the advantages of the Ricoh CX2 compared to entry-level DSLR competitors include: it has a much higher resolution screen (920k dots vs 230k dots), has image stabilization (sensor shift vs none), is newer (august, 2009 vs january, 2008), is much smaller (compact 102x58x29 mm vs prosumer size 129x98x62 mm) and is thinner (1.1" vs 2.4").
However, on average it takes slightly lower resolution photos (9 MP vs 12.2 MP), has a much smaller sensor (1/2.3" 6.2x4.6mm vs APS-C 22.2x14.8mm), doesn't have a viewfinder (none vs pentamirror), users slower contrast detection autofocus (contrast detection vs phase detection) and doesn't shoot RAW.
