Apple yesterday reached a new market value high of $600bn (£377bn).

The iPad maker is the second firm to reach the landmark figure after Microsoft which did the same over 10 years ago during the dotcom bubble. The news comes a few weeks after Apple launched and sold more than three million of the new iPad.

Apple crossed the $500bn mark at the end of February and the $400bn mark less than two months previous to that, according to cbc. Microsoft's record market value was $619bn however it is now worth around $260bn.

Something that Microsoft will be hoping to close the gap between the two companies is Windows 8 which will launch later this year. The operating system will run across PCs, laptops and tablets.

It is likely that Apple will launch its next generation iPhone this year, possibly called the iPhone 5. For all the latest rumours, specs and release dates check out our dedicated page.
