MP3 -- taking the Internet by storm

Digital music encoding technology has swept the Internet. Thanks mostly to the encoding format MP3 -- officially called MPEG 1, Layer 3 -- music files that two years ago would have consumed 30MB to 50MB can be compressed to a fraction of their original size while maintaining good audio fidelity. What used to sound like a clock radio playing underwater has metamorphosed into audio that approaches CD quality. That's enough to make people stand up and take notice.

This boom in consumer interest has won the attention of consumer electronics companies, content-oriented Web sites and large record companies, all eager to ride the crest of the newest Internet phenomenon. As a result, listeners today can choose from a wide array of portable devices that play compressed music (see "Mobile MP3"), whereas last year their only option was Diamond Multimedia's Rio. A huge number of Web sites now offer downloadable audio players and music. And record companies, which have fought MP3 tooth and nail, are embracing compressed music formats other than MP3 that incorporate digital rights management and preserve their profits.

Many people forget that a lot of Web music in MP3 format is illegal. It gets uploaded to sites for unlimited downloading by users who have no intention of paying content owners for the privilege of doing so. Incorporating rights management into audio content will enable record labels to release single songs or complete albums from major stars online, so fans can find and download music legally. Of course, under this model you'll have to pay for the recordings -- either with your credit card or by providing demographic information to the record labels.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
