Treo 650

At the time of its release, a significant number of users experienced problems with Palm's new Non-Volatile File System, or NVFS, based on the FAT filesystem. Compared to the Treo 600, the previous version of the Treo, the Treo 650 used more memory per file as the FAT filesystem rounded file sizes to the next highest 512-byte multiple. Because of the larger file sizes, some users upgrading to the Treo 650 from the Treo 600 were unable to fit the contents of their old device into the same amount of memory on the new device.[4]

To remedy the initial complaints, Palm offered a free 128 MB SD flash card to Treo 650 users.[5] Later ROM updates have resolved many of the performance, instability and storage inefficiency issues.

Other main concerns surrounding the Treo 650 (during its initial release period) were as follows:

• Some users experienced random resets at one time or another. Although the cause was unknown, a complete reset via the Reset button on the back of the phone under the battery door could keep the phone stable and running most of the day.
• Some users also reported problems with the unit's microphone. They claimed that voice clarity on the recipient's end of the connection was poor, akin to talking "inside a cardboard box." (koreth, Slashdot). Users have found that bluetooth-enabled wireless headsets or fixed headsets seemed to be an effective work-around.
• Another problem people reported is that the handset's earpiece made it difficult to hear in loud environments. Using a bluetooth-enabled wireless headset would also take care of this problem.
• Further issues include static or buzzing in the background of a conversation, the recipient's voice sounding buzzy as if they were speaking through a kazoo, and the phone failing to notify the user that a text message was received until the user activated the phone's screen at which point the phone would place a false timestamp on the message and act as if it had just been received.

Two special editions existed of the Treo 650, the first a "special colour edition" released in 2006 with spare battery and PalmOne 256MB Card included, this apparently targeted the Japanese market with extra Language functionality available in the preferences menu.

The second was named the "Black tie" limited edition[6] targeting the Asia/Pacific region, released in 2006 and limited to 2000 units, an all black Silicone coated device celebrating 10 years of Palm, these also carried the "Palm" as opposed to the "PalmOne" logo. The "Black Tie" came with a "multi-function" stylus and a Hard case..

Both however had identical hardware functionality with the original.

The Treo Ace was the rumored code name for PalmOne's Treo 650 smartphone introduced at the October 2004 CTIA Conference in San Francisco. The rumors for this product began on June 27, 2004, when TreoCentral posted detailed specifications and mockup drawings for the product. That article started the flow of hyped demand and interest for the Treo's launch that fall [7]

The current firmware updates for the device contain a directory by the name of Ace_Update, confirming the original internal code name. A string inside the Bluetooth driver file indicates that another internal code name may have been "Ace Ventura", a reference to the movie of the same name.

The Treo 650 was superseded by the Treo 755p (CDMA2000), and the Treo 680 (GSM).
