all I know is when I went to the verizon store to play with the X today, I downloaded quadrant and CPI benchmark from the market onto the X and ran them against my droid. my highest droid quadrant score thus far has been a 1575, and on CPUbenchmark 768ms. the droid x right out of the box, scored an 1135 on quadrant, and somewhere aroudn 936ms seek time on CPUbenchmark. With nyumbers like these, at this point the only advantages the X has are its larger/cleaner screen and the 8MP camera. still, as soon as we get some serious ROMs going on for it, custom themes and kernels, you can bet your ass ill be buying one!!!
Sorry to say but the Droid, overclocked or not is no match for a stock Droid X. Except for the froyo rom and flash, I miss nothing from the old droid. Everything is snappier on the X.
I wouldnt worry too much about the code signing with eFuse, at least I hope so.
The iphone 3GS had something close to it when it was released, FW had to be signed and verified by Apple's servers.....that was hacked and fixed ;)
Anyways, I believe there is always a loophole, just a matter of how much time it will take to find it.
A few things in life you can count on ...Death, Taxes and the phrase "If it can be written it can be hacked"
There are ways to fake signatures. We may have to come up with a surrogate signature to allow a new one to load, basically fake out the bootloader. Only time will tell.
