Shipments of SmartPhones are expected to stay stable over the next four years a research firm said. Shipments from Taiwan, China and Japan of the lightweight ultraportables with screen size of 7 inches or less are expected to reach nearly 80 million units this year rising to about 265 million in 2021. So today smartphone time has come and all manufacturers expect them to enjoy very strong market growth. Smartphones, however, did a lot to pave the way for Ipads and android units. The devices, which began as a convergence of personal digital assistants and cellular phones, introduced consumers to what was possible in mobile communications and web access. We are waiting to see Ipad & Android clones development. Tabs are becoming a must for promotional campaings and two manufacturers launched a 13" and 14" size too.
