Lenovo despite its goals of rivaling Apple in tablets may not break out from other Android competitors in real shipments. Part suppliers claimed Monday that the firm planned to ship between 1.5 million to two million mobile tablets by the end of 2011. Estimates given to Digitmes maintained that no more than 500,000 would be ThinkPad Tablets, while 1.1 million to 1.5 million would be the core IdeaPad K1 model as well as the new $199 IdeaPad A1.
