Despite the decreasing consumer electronics spending on rising energy and food prices, Apple still has a bright future 90 days. The Cupertino, California-based software developer was happy to find out that a survey that measured how consumers would react to its products over the next 90 days revealed good news.

The mid-August survey included 4,400 participants and planned to measure planned PC purchases. Researchers found out that 8% of the questioned individuals answered that they planned to buy a laptop in the next three months, while 5% were planning to purchase a desktop.

Now comes the fun part (for Apple). When the survey subjects were asked what PC they would buy, most of them said Apple’s Mac. Of those who planned to buy a laptop, 34% were thinking to get it from Apple, while 40% of those who planned to buy a desktop were also convinced that Apple suited them better.  More surprisingly (or not), 17% said they were more inclined to buy a Mac because the influence of the company’s hot handset, the iPhone 3G.

The survey was carried out by ChangeWave, probably the best known supplier of e-mail get-rich-quick investment tips. With its monthly survey which questions as many as 15,000 subscribers has also become a quite accurate barometer of trends of technology consuming.

However, although it looks good for Apple, it doesn’t look good at all for the industry.

“Just 15% of respondents say they’ll spend more on electronics over the next 90 days compared to 34% who say they’ll spend less. The net difference between these numbers (-19-pts) is 13-pts lower than at the same time a year ago (Aug 2007),” said Paul Carlton, executive director of the ChangeWave Alliance.

Planned purchases for Dell’s notebooks were 28% (3 points higher compared to July) and for Dell’s laptops were also 28%, down 4 points.  HP was down 4 points to 20% for its laptops since July and 3 points to 17% for desktops.
