· Palm has beefed up its Tungsten business PDAs with two models. The Tungsten-W is top of the range, with a small, built-in keyboards and a phone, approved for Vodafone, which will no doubt acquire the rights to use other Sim cards as well (they'll all work). The Tungsten-C, which has WiFi built in, is intended for people working on sites with hotspots rather than out on the road. Neither has Bluetooth but the Tungsten-W will pick up emails through its mobile phone connection; it's just tough if you wanted to send a document from your laptop without buying an extra Bluetooth card. The C will cost £399 plus VAT, and the W will be around £449 plus VAT, without a contract. New pricing will emerge once it's available with a phone contract.

· E-commerce specialist Actinic has published its third annual survey of the e-commerce market for small business, and it's looking healthier than expected with 71% of online sellers remaining in profit over the last 12 months. Over half of the small and medium sized businesses approached confirmed they would be investing further in technology over the coming year.

· Dell Computers is looking to the lightweight laptop market with its new Inspiron 500M and Latitude D500 systems. The Inspiron is aimed at the very small business or the consumer - someone who has a laptop for business but will also want to watch DVDs and listen to music. The Latitude series is more for the "serious" professional, so you're talking data security and less of the fun stuff. Both support Intel's Centrino technology and include WiFi, with Bluetooth connections available as an extra. The Latitude starts at £899 plus VAT and the Inspiron comes in at £1113.91 including VAT and delivery.

· The drive to help businesses who find broadband just a little too baffling continues. UK online for business, the government agency that aims to get businesses trading electronically, has issued a free information pack about getting online permanently. Called the Broadband Advice Pack, it aims to give a practical overview about what's on offer, and how to measure its potential role in your business, and when and where to start in terms of taking the service up. It also includes a set of 12 case studies so you can see what other people have done. It's available from the UK online for business infoline on 0845 715 2000.

· Do you think your employees are wasting time on irrelevant emails? It can happen and research from Waterford Technologies claims it's costing businesses dear. The company says that 100 employees spending 20 minutes a day would cost a business £32,000 per year; scale the problem down for smaller companies and it's still enough to make quite an impact. Waterford is using the data as a hook for its new email management software MailMeter 2.0. The company says that as well as lost productivity - which, let's be honest, will also happen if you allow a few personal phone calls or let your employees go to the lavatory - unmanaged e-mails can leave businesses liable for lawsuits if their employees were to make improper use of their systems and, say, commit libel. A fully functioning 12-day time-limited version of the software can be found at www.mailmeter.co.uk.

· One of the major issues that comes up when people are considering implementing e-commerce in any form is that of trust: how do you know the equipment you're buying will be secure enough for your purposes? With this in mind, a number of manufacturers - IBM, Hewlett-Packard, AMD and Microsoft to begin with - have formed a group called the Trusted Computing Group. The aim will be to ensure more security goes into hand-held systems as well as desktops, laptops and mobile phones. It aims to complement the work being done by the Trusted Computing Platform Alliance.

· Epson has extended its range of projectors to include the potentially PC-less and networked EMP-735. Coming in at £3499 it has WiFi connection capabilities, is lightweight and will happily take information on a credit card-sized PCMCIA card rather than a PC if you don't want to carry the whole lot around. Slightly less portable is the EMP-7800. As you would expect for £4999 it has a better picture and is more robust, but it's aimed at the "move it from one desk to another" market rather than the "sling it in your briefcase and get in the car" school.
