It's no secret that Hewlett-Packard plans to vindicate its decision to buy Palm by using the concomitant IP, especially webOS, to plot its success in a range of web-connected device segments, including tablets, smartphones and printers. It has now further reinforced its commitment to webOS by suggesting that it no longer has room for other OSes.

According to former Palm CEO Jon Rubinstein, who currently spearheads HP's gadgets business, the world's leading PC maker has scrapped plans of developing an Android tablet. Also, the company will not let Windows Phone 7 infiltrate its smartphone portfolio, despite the fact that the platform belongs to its key ally Microsoft.

HP's tablet and smartphone strategy has been covered in haze ever since it acquired Palm. But a much clearer picture is beginning to emerge. We now know that although HP plans to launch a Windows 7-based tablet, it will be targeted at the enterprise market.

This has led many to surmise that the company wants to placate Microsoft while still leaving ample room for a WebOS-based tablet. However, the Palo Alto computer giant, renowned for its loyalty to Microsoft, will not be so accommodating when it comes to the smartphone market.

HP's Executive Vice President Todd Bradley,  made it very clear in an interview with CNBC that Windows Phone 7 is not part of the company's plans. Instead, it will be relying solely on WebOS for its push in the smartphone market.
