For the laptop I love two twitter apps:
Tweetdeck – this one helps organise your tweets into friends, replies and direct messages.
Twirl – I like this one because of the small space it takes on your desktop.

For the iPhone, I love Twitterlator and Twinkle. Liking Twinkle is a bit like saying you support Manchester United (i.e most purists will hate you) in Internet Marketing Circles. I admit, it’s not the best app, but it was the first one I installed and I suppose that’s like a lot of software – you never forget your first love.

I was recently on holiday in France and found myself doing internet marketing on my iPhone whilst sat in the most beautiful surroundings. It annoyed my family a bit, but building up you twitter following whilst tucking into Margeaux and frog’s legs and concass de tomate in the sunshine can’t be beat! If you’ve not got an iPhone, I have two words of advice for you: Get One.
