IN today's computer market, with its moves towards both mobile computing and workgroup solutions, there is an increasing proliferation of contact management and personal organisation software, also known as personal information managers (PIMs). This trend has become more pronounced as mobile computing has become increasingly popular and executives want their computers to become the centre of their daily schedule. At the forefront of the personal organisation and contact management packages are those designed for individuals. Borland's recently released Sidekick for Windows is one example. Building on a DOS version of the product, the Windows version provides facilities to keep contact information, maintain an appointment schedule, track goals, and keep notes. The cardfile, reminiscent of a file of index cards, can be used for storing lists of information, and the notepad allows notes to be filed in folders for future reference. Cards can be linked with to-do lists, note files or calendar entries and regular reminders can be programmed for birthdays, monthly meetings or any other regular event. Unfortunately, the system is not intelligent enough to point-out conflicts between regular reminders and lone calendar entries. Still, Sidekick offers the basic features most users require in a simple interface which, with an application launch bar that can be used as a Windows' users basic operating environment. Alternately, a Quickmenu feature allows easy access to Sidekick features from within any other application. An inexpensive personal information manager is AnyTime 2.1 for Windows. AnyTime provides a scheduler, an address book and a to-do list, as well as the ability to program regular, recurring event reminders. Where AnyTime is lacking against the mid-range packages such as Sidekick or more expensive packages such as ACT, is its inability to link documents to contact names. But, at a list price of US$49.95, it is not very expensive and is simple to use. A growing area at the high end of the information manager market is network-capable packages which allow whole workgroup scheduling to be co-ordinated on-line. Take CaLANdar 3.0, another Windows product, which is also available in DOS and Mac versions. CaLANdar provides group-scheduling capable of juggling and co-ordinating the schedules of large groups of people. The package features personal and group appointment scheduling along with a task list, a message centre and an electronic method of determining who is in or out of the office. CaLANdar can automatically pick times for meetings so that all participants are available and it features an ''E-note'' capability which allows a note to be sent to another user across the network without requiring a full E-mail package. Another group-orientated information manager package is Tracker for Windows from Australia. It provides for multiple databases and allows complete historical tracking of a business contact including present standing and future plans. Core features include word processing, mail-merge and automated dialling, a feature supported by many packages including Sidekick. Multiple users on a LAN can share databases and the program provides for appointment scheduling and E-mail with many different mail systems. Whichever package a user chooses, they all aim to do the same thing: simplify life by keeping all organisation and schedule information in one easy-to-access place: a computer. Just a second, I'll have my schedule up as soon as the PC boots.
