All of you must be aware that IBM has given itz "Thinkpad" and "Thinkcenter" brands to Lenovo.....
IBM says in itz website
IBM:::Lenovo has the leading position in the fastest growing market in the world. Their acquisition of IBM's PC business makes them the third largest PC supplier in the world. In addition, the people of ThinkPad notebooks and ThinkCentre desktops are now part of the Lenovo team -- the award-winning engineers, the manufacturing teams, the sales representatives, the business partners. In short, the people you know. The ones you count on.

So wht does it mean? May be Lenovo has become the third largest PC supplier in the world, however acquisition of IBM's PC by Lenovo may hit IBM in the long term.....

So How?

People who believed in the brand of PCs by IBM will move to some other brands like HP Compaq or Toshiba or Dell......This will in turn decrease the consumer base of IBM and also Lenovo.....Since the consumers have a percetion that since Lenovo is a Chinese Brand it may decrease the quality of the products of PC parts to maximise on the profit......this aquisition may hit other IBM & Lenovo products as the consumers may stop believing in IBM and may not trust Lenovo completely....

The final outcome of the aquisition of IBM by Lenovo can only written with conviction after one or two fiscal years......
