This year’s edition of the Consumer Electronics Show was one of the most challenging for most manufacturers, since most of them are facing the effects of the economic depression.

Still, visitors could see some impressive pieces of technology in Las Vegas, including inch-thin LCD TVs and high-end mobile devices.

However, it looks like last year’s promising technology, including Blu-Ray and OLED TVs, have yet to prove their success, as the former still struggles to become the industry standard. Nonetheless, customers don’t seem so excited about high-definition platforms, since a Blu-Ray Player still costs about $300.

Manufacturers in the Blu-Ray industry didn’t give up, though, as they showcased various Blu-Ray-enabled devices, some of which were interesting, including the Samsung TV with integrated Blu-Ray, and some of which were rather bizarre, such as the Blu-Ray/VCR player combo.

Still, it was disappointing that manufacturers haven’t yet rolled out any Blu-Ray recorder, as many users are put off from buying high-definition devices, since they can’t record HD content through them, anyway.

On the other hand, Wi-Fi technology seems to be part of every device now, as manufacturers including Sony, Nikon and Casio embedded wireless capabilities into their new line-ups of digital cameras. Still, most of these devices still lack the possibility of an internal GPS module, which is useful in geo-tagging photos.

Overall, even though some of the electronics giants tried to mask their financial problems through flashy products, everybody could see entire empty areas at the exhibition, probably because some of the companies retired from the show after they had reserved their booths.
