This might be considered trolling, but here goes if you are interested.
I had a 7650 for some time, bought lots of software, got a lot of use out of it. I took a risk and switched to MS smartphone (SPV) after getting pissed off with bluetooth crap synchronisation with XP once too many times. I've seen talks here where everyone laughed in a superior manner about the SPV. here's m pluses/minuses if it is of interest:
better screen: bigger, more colours
unlimited memory via SD card
real mp3 player
much sturdier construction (though still too plasticy)
excellent auto-lookup feature, first name last name or any name
"real" IE - at least, better than wap only, of course can add this to 7650 with Opera, but quite costly!
decertification is no longer an issue via Orange decert process
negatives:
small keyboard
no bluetooth (not that it's worth much in the 7650 anyway)
no java (but other options)
no camera built in (but I never use it)
And the big winner: synchronisation really works! Much easier by cable than by bluetooth too, since I never left bluetooth running and had to muck around starting it up on both ends.
Anyway, back onto a hopefully non trolling line of thought. Both phones are first generation products. I think, that after a buggy start, the new firmwares on SPV really make it a lot better than the 7650. Let's not argue that too much unless you really want to. I'm interested in what's coming next from Nokia and MS. Which will be best?
I really like the look of the new samsung series 60 device: looks like a real winner, and I think better than the SPV.
In the MS camp, the ozone devices will support bluetooth and probably have camera built in, definitely a better keyboard. look at the Mitac Mio (if it comes out), the Intel reference design (looks great), the asus. Looks like MS is doing some good stuff.
Between them and the samsung, it would be a hard choice. I don't like the P800 because it is too big and not one handed. What do you think the next Nokia will be? Do you think it will close the gap or crush the competition? If it is better than the samsung, then wow!
I'd like to see:
MMC/SD
800*600 resolution camera
smaller, more quality construction
bluetooth that works, with headset profile
complete rewrite of the sync application
option to sync via cable
wap 2
65k colours
no weird design like the 3650: the 7650 looks great, just too thick/big now
keyboard like the 6800 would be wonderful!!!!
If I had all of that, I'd be back with Nokia. But the sync one is a biggie!
Anyway, that was a way of passing a boring Friday afternoon. Look forward to your flames or ideas.
