It goes without saying that I like business models that offer systems to increase efficiency and optimize performance, which is why I'm Reiterating my Buy rating for VMWare (NYSE: VMW), first recommended on June 5, 2009 at a price of $32.59. If you purchased VMW then, you're up about 20%.

VMWare's mission is to improve the efficiency and availability of resources and applications. Examples include running energy systems more efficiently, reducing capital costs, and improving desktop management and control.

Late Monday, VMware (NYSE: VMW) announced that it will acquire SpringSource, a privately held company. The deal carries a total value of $420 million, which will consist of $362 million in cash and equity along with $58 million in unvested stock and options. The deal is expected to close in the third quarter of the year.

The acquisition is believed to have been made in order to help VMW expand its management software in order to work with what is known as cloud computing services. Cloud computing is a service over the Internet where users have an external company run the applications.

VMware's earnings were $32.5 million, which compares to $52.3 million in the same period a year ago.

TheStreet.com's Jim Cramer says the tech industry benefits because the Obama administration pays it little attention.

When you get a streak like technology's had here -- and I am including the Nasdaq as a barometer of tech, with its 11th consecutive positive close -- you have to ask yourself: Is there something going on that's even bigger than the visible themes? I'm talking something beyond low inventories for semis, new product cycles based on Internet mobile, and valuations that got out of hand to the downside.

And I think I have it.

Washington doesn't care about tech. Tech can do what it wants. Tech's not unionized, so Card Check and arbitration, the next battleground, doesn't affect it. Tech doesn't pollute much, so cap-and-trade doesn't mean much. Tech's not much for pensions or for any help from the government with health care. It has virtually no legacies and is largely 401(k).

Today was another one of those days that if you did not look up at the closing bell or at the numbers in the last hour of the day where there was no clear feeling of a direction. By 2 O'clock we had switched directions six times today. Weak housing data and more job erosion than expected failed to define any trends. And the US Treasury planning more than $150 billion in auctions next week has failed to make any impression either.

Here are today's unofficial closing bell levels:

Dow 7,957.06 +70.49 (0.89%)
S&P 500 851.92 +8.37 (0.99%)
Nasdaq 1,652.21 +6.09 (0.37%)

TheStreet.com's Jim Cramer says Nasdaq is so strong it's downright eerie.

Tech can't be fought here. Because people are partying like it is 1999, when firms used $400 price targets for Qualcomm (NASDAQ: QCOM) (Cramer's Take) and Broadcom (NASDAQ: BRCM) (Cramer's Take) had all the wireless network answers and Apple (NASDAQ: AAPL) (Cramer's Take) had the audacity to think that it could control the music business.

We've seen it going on since the market bottom, the endless driving of tech higher and higher. We get the wireless bottom, thanks Nokia (NYSE: NOK) (Cramer's Take); the personal computer bottom, thanks Intel (NASDAQ: INTC) (Cramer's Take); the gadget bottom, thanks Taiwan Semiconductor (NYSE: TSM) (Cramer's Take); the TV bottom, thanks Corning (NYSE: GLW) (Cramer's Take) and Best Buy (NYSE: BBY) (Cramer's Take); the software bottom, thanks to Oracle (NASDAQ: ORCL) (Cramer's Take) buying Sun Microsystems (NASDAQ: JAVA) (Cramer's Take) for its software and IBM (NYSE: IBM) (Cramer's Take) celebrating its software on its quarter; and the dot-com bottom represented by great earnings from Google (NASDAQ: GOOG) (Cramer's Take) and decent numbers from rejuvenated management teams at Yahoo! (NASDAQ: YHOO) (Cramer's Take) and eBay (NASDAQ: EBAY) (Cramer's Take).
