I had the opportunity to use a SonyEricsson/T610 for a while, and here are my pros and cons (based on BrunoRodrigues' initial impressions, translated and with my own):
It acts (and feels) like a T68i on steroids, with a few enhancements.
Pros:
- Solidly built, sturdy aluminum casing.
- Excellent display (OK resolution, excellent contrast and legibility under all lighting conditions)
- Approximately the same size and weight as an 8310 or 7250i
- Nice features:
- IRDA and Bluetooth with reasonably decent OBEX support (beams and receives GIFs, JPEGs, MIDIs and contact/calendar data as vCard and iCal)
- MMS support for large (64KB) animated GIFs (like the network stats I receive)
- Portrait camera with decent refresh rate (288x352)
- 16-bit (65536 color) screen
- Java MIDP support (but although we could beam .jar files to it from a 7650, none of the really fun ones worked, and wierd stuff happened even on "standard" applets - like mismatched screen/applet sizes, etc.)
- Polyphonic MIDI ringtones (beamable to and from the phone), AMR audio support
- Color WAP browser (still not very intuitive and slowish, but more useable than on the T68i)
- Organizer (calendar understands meeting "locations")
- IMAP and POP3 client (no SSL support, however)
- Very fast GPRS attachment (but the browser renders slowly)
- Auto keyboard lock
Cons:
- It's still buggy (I managed to render all my contacts invisible, with only the selection bar scrolling up and down on an empty screen)
- It's hideously fiddly to do simple operations like sending an SMS (6 or 7 clicks against 3-4 on a Nokia, measured from start - including shortcuts to "new" message - to the SMS actually being sent to the contact you painstakingly picked.)
- You can't assign your own sounds to SMS notifications
- There is apparently to way to define an SMS/MMS distribution list or an easy way to send messages to multiple recipients
- Contacts can only have 3 phone numbers (Home, Work, Mobile) plus e-mail (the Series 60 supports a variable number of fields)
- It's still slow. Slow key response, slow scrolling, slow e-mail parsing, slow browser...
- The browser is WAP-only and not XHTML-capable like the 7250i's
- Counter-intuitive key placement (it's too damn easy to accidentally delete a contact, for instance)
- Overly sensitive joystick (it's too easy to accidentally start the browser, for instance)
- Camera does not support landscape mode and has very low resolution (288x352)
- No way to check estimated battery life
- HUGE, bulky and utterly horrible full-screen dialogs to enter URLs, e-mail addresses, etc.
- No multitasking whatsoever (unlike Series 60 phones, you can't, say, switch from calendar to contacts and compose e-mail during a call)
- JPEG images don't have EXIF tags
Frills:
- SMS Chat mode
- Dedicated buttons for camera, browser
- Supports OTA configuration of e-mail accounts (untested)
- Very neat music editor (a pocket 4-track MIDI sequencer with prebuilt drum, riffs and bass lines that saves songs as standard MIDI files)
Supported Bluetooth services as reported by Mac OS X 10.3.4:
OBEX File Transfer, Dial-up Networking, Voice gateway, Serial Port 1, Serial Port 2, OBEX Object Push, IrMC Synchronization, HF Voice gateway, OBEX Basic Imaging
