A while ago Phonescoop took a look at the i870 smartphone from Motorola, here's a short quote from their full test report:

Many iDen handsets, because they are ruggedized and meant to be abused, are very large. However unlike other phones, the extra size usually does not pack in extra features. The i870 finally packs in many of the features of today's high end handsets in the typical iDen bulk. Nextel and Motorola would like to sell these to executives who have to carry iDen phones but will pay for high-end features. It's more likely that executives will stick to iDen's slim i83x series or the Blackberries. Instead, workers and supervisors who are tired of forgoing the show-off features their friends brag about will be the ones likely to purchase an i870.
