My mum has worked for the NHS for many years, after many years of working with paperwork whilst in the office and at a clients house they were issued with Netbooks during last year. They were issued with Dell Latitude 2120 netbooks with Vodafone 3G sims, at no point was an trial or POC performed amongst the staff (from what I can tell anyway) The feedback from a lot of the staff was that the issuing of the equipment was poorly exercised, the Netbooks were really too small to work easily and effectively. The main feedback was that the Vodafone 3G offering was also poor, the majority of places they needed access there was no coverage or just GPRS.
In my opinion they should have tested these before buying a large amount of hardware and certainly before signing up to a stack load of Vodafone 3G contracts. As far as I am aware my mother and a number of her colleagues have handed back their Netbooks asking to be upgraded to Laptops, however there is no money left in the budget!!
