Samsung Electronics Co, the world\'s second-largest handset maker, said it is on track to meet the company\'s sales target for tablet computers this year as Google Inc\'s Android software expands beyond mobile phones. \"We already said early this year that we\'ll sell more than five times this year, compared with 2010,\" J.K. Shin, head of Samsung\'s mobile-phone division, said at a media briefing in Seoul, without disclosing a sales figure for 2010. \"What we said early this year is still valid.\" The maker of Galaxy mobile devices is among companies counting on Android software to lure consumers away from Apple Inc and take a bigger share in the surging market for touch screen computers led by the iPad. The popularity of Android devices helped Samsung more than quadruple smartphone sales in the first quarter, according to IDC Corp.

Apple sold 9.3 million iPads in the third quarter alone, the company said, reporting profit that topped estimates for the period which ended on June 25.
