I agree - this doesn't make sense for many types of mobile-type applications. But you'd really consider this for really anything that has substantial direct user interface requirements (ie has an actual GUI + full keyboard and maybe even touchscreen interaction). Or maybe you might use this somewhere where you're not super BOM cost or power constrained, with fuzzy requirements, and limited developer resources. Using this class of hardware opens up using 'standard' Linux tools which can potentially bring great savings in terms of: portability, availability of developer resources, ease of development. There may be applications where a 5-10x increase in BOM cost in exchange for not having to hire an embedded guy might be worth it.
