The Register review of the Treo 600 on Orange network

"First impressions with the Orange Treo 600 confirm that Handspring designers have got a lot of things right. Although many of the improvements are incremental, perception is everything and this is the first Handspring that looks like a phone, and does so without alienating loyal Palm users. Most importantly perhaps, Handspring has lost the cumbersome Perspex shield, which became notoriously prone to damage. This allows for a much slimmer device in the 'candybar' form factor. A higher pixel density allows for a smaller screen area, (it's still 160x160) and the 'keyboard' has been further shrunk. It's quite usable, although 'buttons' is a more appropriate description than keys. The headline improvements are the addition of a camera and an expansion slot. "
