Well, I went into CPW today to purchase a new handset. Before buying it the salesperson let me have a fiddle with it and tbh, the KF510 isnt all its cracked up to be. The touch buttons were very sluggish - I had to leave a second between button presses (very annoying) screen and style of handset was very nice.
Because I didnt like that one I asked to have a look at the KF600 (Venus) Again the salesperson brought the phone out and let me have a fiddle - this one was just as bad, maybe not as bad to control, but all the same, I wasn't impressed. The top screen of this handset was alright in terms of screen quality, the bottom, when in use for anything other than the buttons, wasnt so good.
Had I of purchased either of these two handsets, they would have been sold within a week or two, or it would have been thrown out of the window.
Didnt get to see the KC550, however, the CPW literature says theuy are going to stock it some time soon - on what networks, I'm not sure.
