Let the hive mind of Engadget get that for you.
"I'm in the market for a new phone and money isn't a limitation. I'm also not partial to any particular US carrier, but here are some of the features I'd like to have: WiFi, GPS, good coverage in lots of places, push Gmail (a must!), physical keyboard (a must!), a touchscreen, decent battery life and a relatively slim body. And please, nothing that has a fruit logo on it. No offense to the fruit fans, though. Thanks!"
I have the 7501 and didn't buy the 7510 for one big reason, HTC REMOVED the joystick!
Most useful input on the machine!
As for people who gripe it's too big, if you scrap the useless keyboard and just use stylus input, then it fits into your pocket, barely.
How would I improve the 7510?
Joystick
32 or 64GB SSD
Silicone case for carrying without KB
Drop the stupid magnets
Real VGA mod, as standard
Netfront Browser v3.5 (this is Steve Jobs wet dream of a browser)
TomTom maps and software included as standard
Anyway, whenever I pull this out to take a photo, jot some notes or video, people ALWAYS ask about it. Everyone is impressed.
Ultimate power PDA and laptop replacement. Whatever happened to convergence devices? Only HTC has the ballz to make one.
