... and potentially vs. the Z720 lol.

These are the 2 or 3 phones i am definitely upgrading to from my Z540. All three are definitely better but for different reasons. ALL have the expansive memory which mine unfortunately lacks, all upgrade the camera, mine is 1.3 megapixels the f300 is 2, u600 is 3.2 and the z720 is 3. I've seen pictures from the U600 and i believe its an excellent camera.

Other main differences are the style, the f300 is a candybar with two alternating sides, dedicated mp3 player and dedicated phone, i like this idea but as i want a decent resolution camera the 2 megapixels fall back as i want to be able to take wallpaper pictures or photos good enough for A4 print. The U600 is a slide with the touch sensitivity which from what ive seen is annoying but can be accustomed to.

So... lol... any advice please?

My current opinion is F300 for style issues, U600 for the camera and Z720 for affordability while maintaining at least the 3mp and music functions
