The Panasonic MX7 takes up from the MX6. It will have an expansion slot (mini SD card) and this is in addition to the 26 Mbs of shared memory available for use dynamically between the different applications. The 2 mega pixel camera will be a wonder to work with considering that the view finder is a 16 Million color TFT display. The clamshell also has an external display of 65,000 colors.
Thankfully thats not all that the MX7 has improved upon. In addition to GPRS, the phone also has Bluetooth which will allow the user to easily transfer data to and fro from the handset. The Mp3 player (built-in) as a feature makes much more sense for the Panasonic MX7 rather then its other siblings such as the SA6 since this one has much more memory as well as an expansion slot.
The tri-band GSM handset that the Panasonic MX7 is, will be available in the third quarter of 2005. Extremely light at a mere 100 grams and having the capability to record video means that the MX7 is one clamshell from Panasonic that we should seriously watch out for.
