When computer company Psion closed commercial operations twelve years ago, “exceptional” employee Paul Pinnock was entrusted with continuing the service for existing clients.

Building on this expertise to start up Purley Way-based PsiXpda, Pinnock launched their first product – a pocket netbook – at last week’s technological exhibition at the Excel centre in east London.

PsiXpda Commercial Director Joe Layton-McIntosh said: “The interest in our product has been phenomenal.

“At the Gadget Show we had lots of people seeing our product for the first time and walking away with one, and the number of enquiries has been absolutely excellent.”

PsiXpda’s success is partly thanks to the Pinnock’s refusal to allow wider technological trends to dictate his business strategy.

In an industry characterised by the increasingly rapid turnover of novel consumer technologies, Mr Layton-McIntosh says the pocket-sized PsiXpda notebook "goes head-to-head with any laptop product and delivers a business solution".

“It’s a business tool, not a gimmick tool.

“We don’t see ourselves as competing with something like the iPhone – it’s a lovely product, but in a few months time they’ll change it.”

The PsiXpda notebook boasts wi-fi, 3G features and rapid connectivity.

According to Mr Layton-McIntosh "it sits easily in a lady’s handbag" and weighing in at only 430 grams it is "possibly the smallest and most powerful in the world".

Mr Layton-McIntosh says the company’s next step will be to deliver “an even better product – in our industry you have to deliver a string of products.”
