In Evo 2.0, I Want To Have...

I'd probably like..Dual mode LTE/WiMAX radio chip, higher resolution screen, built in storage this time on top of microSD card slot supporting upto 32GB or more. Optional skins or UI or stock Android. Perhaps Google can make that happen with a future Android release.
 
Hmmm... since we seem to be dabling into the world of un-obtanium...

  • Form factor resembling a ball point pen - cylindrical, 4 inches long by 1/2 inch diameter. Nigh indestructible as well.
  • Flexible display that rolls up into the body of the cylindrical chassis when not in use; extends out (unrolls) similar to a roll-up window blind and maintains stiffness of glass/metal when active. Provides ~4"x6" touchscreen area.
  • Graphics performance to match - comparable to multi-SLI/X-Fire gaming systems of today.
  • User upgradeable/replaceable class 10 (or better) onboard memory/storage - 2 TB (standards based compatibility/upgradablity ensured through "bios" like architecture - similar to a regular PC)
  • Nano fuel cell power supply requiring a few drops of water/ethanol/other per week to maintain power requirements - No, Wait, make that a nano-scale "Mr. Fusion" that you can drop a few french fry crumbs into for power.
  • Fully waterproof; even able to be used underwater.
  • Comes with remote nano-laser projector that can be used to wirelessley pipe all video output. For projection as a Heads Up Display on the inside of a windshield, sun/eyeglasses, wall, etc.
  • Wireless sound output - with enough bandwidth to handle full 7.1 surround raw streams to whatever output device you wish, including bio-implantable audio in/out interface. Hell, let's do this with video too - pipe it directly to the visual cortex of the brain.
  • Auxiliary sensor and video input - something like a nano scale remote video/gps/compass. Think about mounting this spec-of-dust sized thing on a pair of sunglasses, along with the HUD micro projector projecting to the inside of the lens(es) and using the processing power of the phone in your pocket/purse/backpack to have real-time HUD of a augmented reality visual overlay, whatever you're doing.
  • Doesn't get any warmer than +10 degrees over ambient temperature during full, 100% operation.
  • CDMA/GSM/WIMAX/LTE/other radio capable - No, wait... might as well just spec it out for subspace connectivity. Dynamically allocated bandwidth no less that 25 MB/s up/down - minimum (of course.) And no data caps, of course.
  • Oh yeah, make the thing cost less than... $50 for the device; $50 all-inclusive monthly plan.
  • Ummm...

Yeah, so anyway... :D

Realistically
- super amoled
- retina display
- double the battery life
- gorilla glass on front
- 12 MP, 3200iso, with macro function, auto-focus camera
- improve 4g, 3g, Wifi antennas and performance
- LTE if sprint changes to LTE
- larger screen, by making the screen go to within 1/32" of the edge along the longer size, but keep the same form factor.
- thinner and lighter
- wireless charging (fuel cell works too if 1 week or so per fill-up)
- apple power book magnetic type connection for USB & HDMI - No more port problems!
- stereo speakers
- touch display - see Electrotactile Arrays for Texture and Pressure Feedback During Robotic Teleoperation | Hizook look at 1:30 in the video.

Oh, and it should be free with a 2 year contract:)
 
- Make the phone half as thick
- Make it weigh about 30% less
- Same screen size but smaller length and width of phone (there is room for improvement with the dead space surrounding the screen)
- Dual microSD slot access without having to take out the battery
- Improved camera and video
- Integrated skype
- No fps cap
- Improved graphics capability for gamers
- 72 hour battery
- No more cheap plastic (the new iPhone looks like a nice piece of hardware in comparison)
- 2.0ghz processor
