DeviceMap has several advantages : apart from the plain $ cost, there
is also

a) cost of resources :
- - DeviceMap's footprint is minimal
- - DeviceMap does not depend on elaborate caching
- - DeviceMap has *no* dependencies

b) maintenance cost :
- - DeviceMap's code-base is microscopic
- - regex based systems all contain hard-coded regex patterns.'Radical'
new user-agents (like IE 11, following Mozilla) require resource and
code updates
- - regex based systems all depend on building 'chains' of parsers or
code-paths to follow. 'Special' new devices/agents (NetFlix, I read
plans a dressed-down WebKit based user-agent, for example) require new
code.

I imagine DeviceMap securely embedded or plugged in web-facing systems
or as dedicated API, depending only on resource updates (XML but also
smaller faster formats like protobuf -- my favorite -- or MessagePack).

I had better get busy with the promised test data and results.
On to the 1st release...
