Palm’s latest Treo handset - the Palm Treo 680 promises the same form factor as its Treo 750v model launched last year but without 
the 3G connectivity and without the Windows Mobile 5 operating system. It’s a sort of cheaper, less punchy, version for those still wanting to use the Palm OS and not really fussed about having 3G connectivity to surf the web or download your emails. The Treo 680 smartphone is the fourth smartphone launched by Palm in 2006 and comes hot on the heels of the recently announced 3G enabled Treo 750v smartphone, Palm’s business-oriented smartphone for Europe, that’s still awaiting a US launch.
Like the 750v the Treo 680 sports a full QWERTY keyboard, a 320 x 320 screen and loses the stubby aerial on the top. However is quad-band rather than 3G. Palm Treo 680 smartphone Review - Pocket-lint.co.uk
