PROs:

1. Large screen (It's really HUGE!!), colourful view (although Samsung has a better view with 65K colors, while nokia 3650 has only 40K colors, but trust me, 40K is clear enough even for the photos!!), bright enough (can still see under the sun)

2. Convenient buttons with the "call" and "end" buttons (Some phone doesnt have separate buttons for call/end), 4-way Navigator button, Menu button(just one click and u can choose whatever applicants u want to use eg. Calender, Real One..), Camera button (just click it and start to take a pic !), Tzone button (for the GPRS surfing, emails..)

3. Multimedia Message Service (MMS) which is really GREAT! Send photos, video clips, or soundclips to your friend's mobile phone (his mobile phone must be compatible with MMS service, and has signed up for the MMS). You may prefer to surf net with your computer, but it's really convenient to surf net and check your emails regularly (or u can set up to have email alerts!) while walking on the street, eating, waiting for bus..

4. Bluetooth technology, can be used with PDA, digicam, and laptop (which have bluetooth as well) to connect for wireless internet at your PDA/laptop...etc Java Symbian (which other phones doesn't have!!)

5. 3Mb built in Memory and 16Mb Memory card, which allows for large storage of photos, notes, to-do lists, phone books (can store nearly unlimited phone numbers).. etc

6. Surprisingly, the Image quality is much better than i've imagined. Definitely clear enough, and even when sending to emails.

7. Have "Loud speaker" function, where u can use it just like a Walkie Talkie, without having a headache after chatting for hours!

8. Has Photo caller ID !! (which Samsung doesn't have !!) I heard this only works with T-mobile, but i'm not sure about it, coz I have no problem using it with T-mobile..

9. So many other functions to use.. eg. To do list, calendar (with time and alerts), notes, recorder, Games, Real One player, currency converter, calculator, composer...

CONs:
Well, I would say that although it's a Triband phone, thus u can use it around the world ONLY IF you're using a US wireless service (which is quite expensive to call from overseas for a long period). You can't use this phone to subscribe another wireless service in other country (eg. UK, Asia).

The T-zone for surfing net is much slower than a computer, but still okay for checking emails.

The keypads are weird. Take me very long time to type a sms/email. Try to get familiar with it !~

The size is undoubtly bigger than other phones, but still small enough to fit in your pocket. Compare the features of this phone with other small-sized phones, and u will know why is it worth !!

Reception:
The most important requirement in my book. The reception is very good compared to some of the smaller nokia models. Extremely impressed.

Size:
The previous unit I owned was probably the smallest phone ever manufactured (Nokia 8290), if you discount the one Ben Stiller uses in the movie Zoolander. I really liked that phone since I am a small person and I can slip it into my pocket without it feeling bulky. This phone is almost twice as large as the 8290, but not as big as some reviews have made it out to be. I am still getting used to the size, but for the features it packs, I can live with the slight bulkiness.

Keys:
The keypad is definitely weird, but I am already used to it. So I should stop complaining.

Camera:
I have never owned a camera phone before, and the in-built camera is pretty cool. The resolution is adequate. People have to realize that the primary function of the camera in this phone is to take silly pictures and email them to friends and family. If you are really looking to take high resolution pictures, wait a few more years or use your digital camera. I am sure this feature will change the way I use a cell phone. Isn't technology wonderful??

User Interface:
I am used to the simple user interfaces of the 8290 and 8260. But this one phone packs a lot more features and so is a little more complicated, but is still a breeze. I like the level of customization that is possible (e.g., it allows you to specify two hotkeys for the most commonly used functionalities; unique ringtone for every contact in the list )

Memory:
Approximately 3 Megs inbuilt and 16 megs memory card. That is pretty adequate for my intended usage of the phone.

Email (t-zones):
You need to sign up for T-zones (the basic ... version for 1MB/month or ... for 10MB/month) to access the internet features. T-mobile has a promotion right now with the ... plan (first month free and unlimited data transfer during the month).
It was pretty straightforward to setup pop mail accounts. I setup three different pop accounts that i use in less than five minutes. The only trouble I had was that T-mobile does not explicitly state the SMTP server information and I had to dig around for this information. Nevertheless, the phone handles emails well. I only intend to use this phone for emails when I travel and do not have internet access available for my laptop and I think this phoen is adequate for that purpose.

I think 1MB/month is not sufficient if I plan to check email occasionally and email pictures captured by the phone. But that is a T-mobile related issue and not specific to the Phone.

Misc: Not crazy about the video recorder. The polyphonic ringtones are cool. I do not own a mac, so bluetooth is kind of useless to me at the moment. The color screen is adequate for all practical purposes. Compatibility of nokia chargers and earphones among various nokia models is a bonus as now I have three chargers from older phones and I have them at home, work, and my bag and a charger is always handy.

Summary: This is the first feature-packed phone I have bought and I am pretty impressed. The only cons are the slight bulkiness and, it does look cheap. The inbuilt camera is pretty cool and the reception is awesome. I still have not tinkered with some of the features, but am very satisfied with what I have seen so far. Would give a 4.7/5.0

PROS:

- Highly customizable. You can create your own labels for the phonebook and you can also organize your menu to the way you want. The housing covers are also a nice bonus. The soft keys can be used as shortcuts for whatever you want them to be.

- Camera: It's great. I never thought I would use a camera phone, but I have. Looking at apartments last week, I took pictures. I was in the bookstore and took pictures of books I was interested in, so I could later go online and read reviews about them. I've taken pictures to schedules posted at the bus stop. I could go and do my thing and no the options for when the buses come. It goes on and on.

- Video Recorder: WITH T-MOBILE YOU CAN RECORD SOUND ALONG WITH YOUR VIDEO! NOT WITH AT&T OR CINGULAR (to my knowledge), ONLY WITH T-MOBILE. This is fun to have to. My roommate's cat is crazy and I wanted to prove what an aggressive cougar she is. I took a video of her going after me when I was trying to feed her. Sound and all.

- Size: I put it as a pro because it's much smaller and lighter than you'd imagine. I was really surprised when I got it, especially how light it is. People seem to discount that the antennas attached to other phones should be counted as part of the phone's size also. With all my antenna phones, I was afraid of putting it in my pocket for fear of breaking the antenna.

- Sound quality: With all my Samsung phones (and I love Samsung) I got splotchy reception in my apartment. I expected worse out of the 3650 (with the internal antenna) and got better. Much better.

CONS:

- Nokia didn't make the extra step to make a 65K color screen. My S105 had 65K colors. Although it's a lot more, the difference is hardly noticeable, so it's not really an all out con.

- Keypad: I love the keypad because it's different and unique. It does take getting used to - especially texting.

All in all, it's a fantastically fun phone. It sure does turn heads. I'm almost self-conscious using it because as soon as I pull it out, people are looking at it. It's that hot!
