This community wiki is for determining a list of good mobile phone choices if you are "nerdy" (definition follows.)

As a point of reference, the almost two years old N95 8GB will be used. Mostly because that's what I can most relate to since I've had it since it came out. Today, iPhone and other modern mobile phones really out-shine it in usability and interface. However, it still does everything I want it to do (and here's the definition of "nerdy"; modify as needed):

• Syncs contacts, calendar, tasks and mail in the background
• Can run multiple installable applications in the background (Google Maps with Latitude, for example)
• Good amount of space for music etc.
• Lets you develop your own little toy applications (Python; not to mention it can also run an Apache server with a public URL!)
• Tethering!
• Supports Flash (maybe not very important, but it has its uses)
• Has a manufacturer that believes in the nerdiness! (The people at Nokia Labs make lots of cool stuff and share early versions with the community and are generally open)
• A high resolution screen (at least 320x240)
• Special hardware features such as an accelerometer and GPS

What's missing from the N95 8GB but still qualifies as good, "nerdy", qualities:

• 7.2 Mbit/s (or faster) internet through HSDPA or HSPA+.
• A good web browser that can do most of the stuff a desktop browser can (especially render sites properly and run JavaScript correctly)
• Touch (especially multi-touch)
• More special hardware features such as a compass
• Intuitive and fluent user interface (Shiny stuff)
• Ability to configure it to trust root certificates of my own choice
• A processor fast enough to run Quake 3! =)
