While Apple’s iPad continues on its warpath, other tablet makers are not finding it quite as easy to offload their Android and Windows slates — which is understandable, considering they’re doing it wrong. While Apple managed to ship 9.25 million iPads last quarter and some retailers are still having trouble keeping inventory in stock, other consumer tablet vendors are reportedly having a difficult time pushing their wares past retail channels and into the hands of end users. Even the success stories among tablet vendors are exhibiting less-than-stellar sell-through, with companies like ASUS, creator of the popular Eee Pad Transformer, said to have left nearly 30% of the 700,000 tablets it shipped between May and July on store shelves. As a result, tablet vendors like Samsung, Motorola and HP will be forced to lower their prices in an effort to bolster weak sales, DigiTimes reports. HP has already offered two limited-time sales on its TouchPad tablet since it launched just last month, and now the company has permanently shaved $100 from its tablet’s price tag. Motorola also recently lowered the price of its XOOM tablet, leaving the 32GB model priced evenly with Apple’s 16GB iPad. DigiTimes says its sources are anticipating two more waves of tablet price cuts this year, one in September and another approaching the holiday season.
