Some people think that the limitation of the Firefox phone is the lack of 3G. But many users only need basic messaging and Facebook, and they will use wi-fi for uploading pictures, watching videos, etc.
Yes Firefox Spreadtrum is having good interface as compared the Nokia Chromium OS, also the features as compared to the price is the way exceptional WiFi, 2MP Camera and Dual Sim is amazing for the first time smart phone buyers. This phone will really extend the actual reach of internet to many users for whom access to internet is not affordable as on day.
Nokia 220 is an interesting breed. It supports 2 most popular apps for a lot of people. If it supports Whatsapp and/ or other messaging software, it could satisfy a lot of consumers especially in emerging market.
However, a $25 smartphone with Firefox OS is even more attractive. I wonder what's the capability with the specification.
What are the engineering and design challenges in creating successful IoT devices?
