Apple has another weapon in its campaign to end Mac users' reliance on anything Microsoft. Its new presentation software, Keynote, takes on the formidable foe PowerPoint and exploits some of the cracks in that program's Goliath-like armour. PowerPoint is the most lacklustre component of Microsoft's Office X for Mac suite, so its drab colours and stuck-in-the-'80s themes are no match for Keynote's crisp, fresh graphics. And whereas a single PowerPoint licence goes for £300, Keynote costs just £79 (inc. VAT) and can import and convert PowerPoint files. PowerPoint does offer some wizards and clip art that Keynote lacks, but we can live without them -- especially given the price. If you're looking for presentation software on the Mac, give Keynote a try.
