Business / brand name with generics as redirects and/or with generics as separate minisites.
Generic keywords are great for driving traffic / easy direct-navigation, but often lousy for product differentiation / difficult to build a "generic" keyword into a brand.
Ponder these examples of popular unique brands verses keyword names - most often the unique brand, even when seemingly meaningless (ie. Amazon.com for books / media) wins out ... some examples:
Search engines: Google, Yahoo, Live.com ... not search.com
Books / media: Amazon.com ... not books.com nor music.com
Domain registration: GoDaddy, eNom, and numerous others are far more popular than domain.com or register.com
Cell phone service: Verizon, T-Mobile, AT&T (formerly Cingular), etc not cellular.com
Cell phone units: Nokia, LG, Motorola, etc not cellphone.com
Computers: Dell, Gateway, HP, etc not computer.com
Rambling on ... point is often a business should utilize / leverage both their unique brand(s) and related keywords in cyberspace.
