'Our one big complaint about the phone: If you want to dial a number that's not in your address book, you have to open the screen first so that you can access the keyboard/dial pad, then close it again to use it as a phone--a really cumbersome setup.'
'We were actually quiet surprised with the Sidekick and its performance.'
'The phone was able to take a 4GB Kingston microSD card to hold music and video, and it comes with Roxio software that automatically transcodes your videos into a format that works on the phone.'
'A few dropped calls when switching between Wi-Fi and GSM'
'Expensive.'
'For those who are technically minded, UMA works only with GSM and it's technically not VoIP as are SIP services.'
'The phone's contact list is a bit more appealing than other handsets we've seen from Nextel, such as the Motorola i615 , and it supports while-you-type searching.'
'under direct sunlight the display is almost illegible.'
'fat and sluggish'
'Poor pictures from camera option'
'Due to a bundled client, companies with Avaya Communication Manager can already connect the Nokia E50 directly to their company phone networks, enabling the smartphone to work like a traditional office phone.'
