With Skype you can not only have voice chats on your computer – just like telephone, only for free – but also make real phone calls at much lower rates, using the SkypeOut service and paying with Skype credit. Besides voice chats, Skype also includes standard IM functionalities (written conversations, emoticons, user avatars and so on) and also lets you have group video conferences.

Improved video interface

These video calls are precisely the main focus on Skype's latest version. The program's interface has been completely redesigned with video conferences on mind. This means it's been made wider so that video fits in perfectly with your written chat, your contact list and a toolbar to manage conversation. The new interface is transformed when you make a call, getting rid of all the clutter, so you just see the video images, and controls. Group video is still being tested in this version, and it's pretty cool.

The sound quality during our testing was perfect: loud and clear. Video sometimes appeared a bit pixelated, but nothing we couldn't really deal with. There was also one nice detail, and that's the ability to see your own video image built-in on your contact's video, and the option to take a snapshot of your own image.

Facebook integration

The other major development is Facebook integration. This is a pretty big thing, as not only does it give you your news feed in the app - anyone can do that - but adds call and sms buttons to any of your friends who share their contact numbers. If you’ve paid for Skype minutes, you can call your Facebook friends, and if they’re also signed in to Skype you can call them for free. One of the best new features is the automatic call recovery - drop a call and it’s put in pause. Restarting it is now really easy.

Skype 5 features a complete interface overhaul that now focuses more on video chats, and also adds some handy improvements to the way you communicate online.

Multiple protocols and devices

Known variously as Gtalk, Google Talk, Gchat and Gmail Messenger, this compact, functional app is all you need when it comes to staying in contact with your Gmail friends. Not only does Google Talk support Google accounts, it also supports a variety of other protocols and apps. In other words, you can log in with accounts from Jabber, Pidgin, Miranda, Psi and Trillian.

As well as supporting lots of protocols, Google Talk is also available for lots of devices, so even if you are chatting on your desktop, you'll be able to keep in touch with your friends on Android, iPhone and Blackberry. Even though not explicitly supported, you'll also be able to use Google Talk on Mac and Linux, as long as you use the browser version.

Nice layout, easy to use

Google Talk is an attractive app and very easy to use, although its bright, almost childlike appearance is looking a bit old-fashioned these days. There are various themes available from the Settings options, although they have more impact on the window layout and are not strictly "skins". You'll also be able to choose your status, picking from Available, Busy, and Idle, as well as custom messages and the option to show your current music track. Google Talk also notifies you when you receive new emails.

Adding and chatting with contacts with Google Talk couldn't be easier. Double click a name to start a conversation, and a new chat window will appear. If you see a little telephone or video camera icon beside the contact's name, they are also available for phone or video chats, but you'll need the Video and voice plug-in to do this.

Google Talk has many of the features that you'd expect from an IM client. You can add, block, rename and remove contacts, send smileys, and customize the way you see your friends online. If you look under the more technical settings, you'll also be able modify notifications and connect to the service using a proxy. It's not overrun with options, but most people seem to appreciate the resulting simplicity and light resource use.

The downside

Even though Google Talk is the go-to IM app for thousands of people, long term users can't help feeling that Google Talk is pretty low on Google's list of priorities. It works perfectly and is a great app, but that's because it was well made and ahead of its time when it first came out.

Google Talk hasn't been updated in what seems like years and, with the exception of the VoiP features added in recent times, the program feels a little bit forgotten. This has no impact on usability for Gmail users, but it does feel like Google Talk could do with a little more loving care.

If you're a Google User who wants to IM, you'd be mad to use anything but Google Talk.
