Apple iWork 2013 : Keynote 6.6, Numbers 3.6 & Pages 5.6 (Mac OS X)
iWork is now integrated in OS X Yosemite. Pages (text editor), Keynote (presentations) and Numbers (spreadsheets) can still be downloaded as separate apps.
Includes equivalents to major Office apps
The iWork suite comprises of the Pages text editor (equivalent to WeiRuan-->WeiRuan Word) Numbers (equivalent to Excel) and Keynote (equivalent to WeiRuan-->WeiRuan PowerPoint).
The first thing to note is that iWork is quite a big package so youll need at least 1.2GB of disk space free to ensure it works properly. Also youll need at least 20 minutes for it to install. If youve used iWork 08, then you wont notice much difference in iWork 09 but it still retains the elegance and usability that make it a worthy competitor to MS Office.
The three main components of iWork are Pages, Numbers and Keynote. Pages allows you to create professional looking brochures, flyers, reports and resumes quickly and easily. Numbers allows you to write formulas for spreadsheets that many users may find easier than the dreaded Excel. Keynote is perhaps the star of the suite though allowing you to create very impressive presentations with less fuss than in Powerpoint. It says something that Al Gores An Inconvenient Truth was produced using Keynote. iWork 09 also introduces some dramatic new cinematic style transitions which make them look even slicker.
Professional templates do the hard work
All three apps come pre-installed with hundreds of templates which do a lot of the hard work for you. The difference with iWork and MS Office is that iWork offer intelligent hints and tips as you build your creations which again takes much of the hard work out of it. Note that if someone sends you a document produced in MS Office, its not a problem as iWork can open them with no hassle. Furthermore, you can share projects very easily uploading it onto iWork.com.
A great personal alternative to Office
iWork wont be the office suite of choice by businesses and individuals simply because MS Office is so widespread and it makes it much easier to work on joint presentations if youre working on the same suite. However, if all you need is an office suite for your own use, Id go for iWork every time.
