Today on the Marketplace Mid-Day Update, we speak with Marketplace tech reporter Queena Kim about the state of the declining PC industry. Rumors are abound that Microsoft could chip in as much as $3 billion to the buyout of computer maker Dell.

We also spoke with Wall Street Journal reporter Kate Linebaugh about how U.S. firms are stashing foreign cash in American banks. It's estimated that could total as much as $1.7 trillion in foreign assets.

"Companies have been expanding overseas and a lot of their income is earned from developing markets around the world or from Europe," Linebaugh says. "It is just being kept in U.S. securities or bank accounts or U.S. government bonds because they are very safe."

Also on the program, we visit the second-most popular tourist destination in Florida. Hint: It's not what you think.

And finally, McDonald's reported solid earnings today thanks to the popular return of the McRib.
