Laptops contain sensitive business data worth an average of £260,000, according to a survey contracted by iBahn, a provider of secure hotel broadband services.
In addition the study found that the average value of personal information on travellers' laptops is around £160,000, and that 39% of respondents had been hit by some form of malware while at work.
It also found 40% of respondents use open or unsecured Wi-Fi connections in any given month, and that only 32% said the Wi-Fi connections they use in hotels or conference centres are "somewhat" or "highly secure."
The iBahn study was conducted by FGI Research from 5 to 16 April this year.
Four hundred and ninety-one people responded, all of whom use a laptop or PDA and stay at least one night in a hotel monthly. About 18% of respondents were managers. FGI Research used its SmartPanel to assemble the "most representative sample possible."
