NEW YORK (TheStreet) -- It has been a couple of weeks since software giant Microsoft (MSFT) - Get Report told its OEM partners Hewlett-Packard (HPQ) - Get Report and Dell (DELL) - Get Report they now have to start carrying their own weight.

In revealing

its plans for the Surface tablet

bearing its own name, Microsoft has essentially

proclaimed its hardware independence

. The implication is that it wants to stomach the responsibility for its own successes and failures -- the same model that has helped


(AAPL) - Get Report

become the largest company in the world while sending

Research in Motion


in a

death spiral toward irrelevance


In fact, the so-called "unified platform" has been so successful for Apple it has


(GOOG) - Get Report


working hard to emulate it

by essentially becoming a rival to its own partners in


(AMZN) - Get Report



with its own tablet in the Nexus 7.

It appears things have turned upside-down as the technology sector is abandoning an old working concept, one that was akin to the separation of the branches of government.

For years it's been understood that original equipment manufacturer partnerships was the effective model -- splitting the makers of hardware from those that specialize in software. The question is, where does this new change leave the hardware vendors, now apparently under attack by their own software partners? If software companies are now entering hardware, what is left for them?

Before we answer this question -- one that can venture into a number of directions -- we need to make a few safe assumptions while also seeking to understand it is very possible the changes we are witnessing can very well signal the beginning of the end of the PC era.

What we will be left with is a new age of computing led by the three-headed monsters of Apple, Microsoft and Google, an era (similar to the rise of the PC) that will feature a rash of consolidation just as when HP acquired


and lesser-known brands such as



Digital Equipment

went defunct.

But it seems this new shift in model has been anticipated -- neither Hewlett-Packard nor Dell appear surprised. Their responses have been something like, "Since our software partners are entering hardware, we need to respond back by entering software."

In fact, Dell has been on a shopping spree of late by having spent $2.4 billion dollars to scoop up

Quest Software


. This comes on the heels of its recent acquisition of


for an estimated $1.2 billion.

Essentially, these transactions, which also included buying

Wyse Technology

in April (this year),

Perot Systems

(in 2009),

KACE Networks

(in 2010) and in particular its recent deal for


, suggest that for some time Dell has seen and read the writing on the wall that says "Adapt or die." Clearly, it's trying to avoid the latter. But will it be enough?

Meanwhile, Hewlett-Packard has been making its own preparations for the future -- except in the process it has also been hampered by playing musical chairs in the CEO's office. Luckily, it appears to have found a new leader in Meg Whitman who so far appears to have placed the company

on a path toward a solid recovery


As with Dell, HP has been on a shopping spree of its own in anticipation of this new trend. Among its recent software acquisitions include




(in 2010) and most recently scooping up

Autonomy Software

for a little over $10 billion in cash.

In addition to these moves it has recently put plans in place to consolidate its PC and printing divisions while have also announced a reduction in its workforce - moves that the company anticipate will help it save $3.5 billion in expenses over the next couple of years.

Bottom Line

For HP and Dell to emerge successful as the software companies enter their space, their challenge will be to discover ways to expand their high-margin segments such as services, networking, storage as well as figure out ways to leverage their recent software acquisitions to synergize not only with their existing businesses but also to address the new enterprise phenomenon that is known as "the cloud."

This will be no easy task as Apple, Microsoft and Google are not just going to roll over and play dead.

Nonetheless, what Dell and HP have done is respond to the threats while placing themselves on a path towards restoring lost credibility and returning value to shareholders. While it is still too early to proclaim their resurgence, Wall Street should give them their due credit and investors should give them some time.
