Both Nokia N97 and Nokia X6 has:
Same 2G and 3G network coverage, Same amount of Internal memory and RAM (32GB of storage and 128 RAM), GPRS class 32, EDGE class 32, 3G (HSDPA) 3.6 Mbps, WiFi 802.11 b/g, Bluetooth and microUSB, Same UI (Symbian S60v5), Same CPU speed (434 MHz), GPS, Java, TV-Out,
Additional Feature on the camera
While both of Nokia X6 and N97 have the same 5 Mpx camera with Carl Zeiss optics with autofocus; the difference between the two is revealed in the Flash feature. Nokia N97 only uses single LED flash, while the Nokia X6 uses double. So even though I’m not that satisfy (I was hoping Xenon flash on X6); but I think the X6 will perform better in low-light condition.
Firmware
The Nokia N97 is a bit criticized by some people due to its unstable software and the lack of constistent kinetic scrolling. And rumors are saying that the X6 will use the improved version of the N97 firmware, so hopefully the problems will be solved. But you can upgrade your N97 firmware too.
Nokia X6 is US$100 cheaper then Nokia 97. The price may vary but when i purchased its was more then US$100. I'm not saying the '97 is bad. It was my first choice but i didn't want buy slides type mobile. I'm not sure but '97 do hav also touch screen funtion.
