Dell, Inc. (NASDAQ: DELL) made quite a few changes in 2007. Its founder, Michael Dell, came back to lead the company, it entered the retail market in the U.S. in a large way and it began introducing more appealing laptop PC designs to cater to the consumers who love choice. As a result of all these changes, CEO Michael Dell is now predicting a strong second half for Dell in 2008.

Dell mentioned that the company he founded would "have a big second half" based on numbers so far in 2008. Dell's consumer business sales rose 20% for the Q1 period ended on May 2, and Dell is predicting even stronger growth for the current quarter and the Q3 period as well.

Based on all the strong moves Dell made in 2007 and into the last fiscal period, he could be right. Dell's retail partnering in the U.S. and with Gome in China is going to mean some wicked business the rest of this year. However, competitor Hewlett-Packard Corp. (NYSE: HPQ) recently unveiled one of the largest product refreshes in its history and Apple, Inc. (NASDAQ: AAPL) just moved past Taiwan's Acer to take the third spot in U.S. PC sales. It won't be a simple task for Dell to keep this segment growing like it has predicted.

And that's just the consumer PC business. Dell's efforts in the large market area that includes Russia, China, India and others grew at a 58% pace in the company's Q1 period, and a grouping of emerging markets accounted for 12% of Dell's sales in the Q1 period as well. Add that to its push into a huge "cloud computing" marketing towards customers who order hundreds or even thousands of servers at a time, and Dell has many tricks up its sleeve to keep things growing at a decent pace.
