What business can expect from Mac OS X Snow Leopard

Tighter integration with Exchange and the end of AppleTalk are main changes for the enterprise

What else has changed

In many respects, based on what Apple has shown at WWDC 2009, using Snow Leopard is likely to be a nonevent for users and IT, outside the newfound ActiveSync and Exchange 2007 support. The really big changes are under the hood: a sped-up Java processor; a new parallel-processing architecture called Grand Central, to support multicore-enabled applications; the ability to steal processing capability from graphics cards when you're not playing games; and a faster video engine in the revamped QuickTime X engine. Optimized apps will thus run faster on Snow Leopard due to processor optimization, and Web, video, and animation should run faster, period.

The UI is nearly identical to Mac OS X 10.5 Leopard, so there should be almost no learning curve for either IT or users. (An updated Safari 4 has the most notable UI changes.) But there are a few small changes to be aware of both as a user and as someone supporting users:

There are new controls over text input for Chinese languages, including the ability to use gestures on a newer Mac's trackpad to write Chinese characters, picking up an iPhone capability.

In the Dock, if you click and hold on an app's icon, you see images all the windows open for that application (something Windows 7 will also do when it ships in October). The Stacks feature in the Dock now lets you drill into subfolders.

In Icon view in the Finder, there's now a magnificiation slider, and the icons are live previews, so you can play movies, page through PDFs, and so on.

There are likely to be a raft of similar-scale enhancements in the final version when it ships later this year (upgrades start at $29 per user).

The latest Mac OS fits that much easier into business IT

Despite its public diffidence about enterprise adoption, Apple has made Snow Leopard an easier fit for the enterprise. ActiveSync support, the death of AppleTalk, and various security enhancements are of little use to the consumer audience that Apple formally targets.

Ironically, the lack of fundamental changes that could break applications or require user retraining should also appeal to enterprises -- especially those whose mixed environments will soon require significant resources to accommodate the coming shift from Windows XP to Windows 7. Either way, organizations that use Macs will be able to ease their Mac management, and those that are considering Mac adoption now have a few more obstacles removed.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

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.

As a freelance writer who is always on the go, I like my technology to be both efficient and effective so I can do my job well. The HP OfficeJet Pro 8730 Inkjet Printer ticks all the boxes in terms of form factor, performance and user interface.

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.
