Absolutely.  The example given for the Top 10 was too simple to benefit (unless of course you're trying to port something to/from a system that does not support the TOP keyword).  If you want to sample values from every 10th item, or need to grab the #s 11-20; or #s 31-40 (or combinations, etc.), ROW_NUMBER is much easier to use (and often considerably faster) than most alternatives.  The alternatives often include a lot of complex self-joins to "number" the rows to achieve this same effect.
