'weak, 2G-only signal'
'First impressions are extremely favourable: this is a superb looking smartphone with strong lines and a gorgeous screen.'
'The trackball on this phone seemed especially sensitive and intuitive in our hands-on tests.'
'questionable battery life'
'Integrates social-networking well.'
'The thickness is less of an issue than we anticipated as well.'
'The 624MHz processor lags behind the circa 1GHz chips seen in its rivals, internal memory is limited to 4GB and video recording is just VGA at 24fps, when 720p HD has become the new smartphone minimum.'
'The Sony Ericsson Xperia X10's data performance was spotty.'
'The microUSB slot is located at the top as well under a dust cap - this is a little awkward to get off at times, and has a frustratingly short leash to keep it in place - meaning you have to really wedge it out of the way to connect up the charger.'
'But the videos are pixilated and lack vibrant colors.'
'When all the widgets are active, the constant flow of information can be overwhelming and somewhat of a (forgive us) blur.'
'The on-screen QWERTY keyboard, available in portrait and landscape modes, was not nearly as accurate.'
'Battery life was also dismal.'
'And its non-MOTOBLUR functions are equally well-designed.'
