Under the Hood: Evolution of the smart phone
Teardown 3/3/2008 1 comment
It is interesting to look at the different ways that HTC and Nokia, two companies that have very competitive and successful smart-phone offerings, arrived at their latest products. HTC used its background as a PDA manufacturer to create the TyTN 2, essentially incorporating phone functionality into a PDA. Nokia came into the smart-phone market from cell phones, so it needed to find ways to increase functionality without substantially increasing the size of its latest phone, the N95.
