50 bucks flat rate for everything is going to change the hell out of the US market if its actually the case. It undercuts the bejebus out of pretty much every other company
the US market is changing and pulling a couple of good units out with contracts before it gets even more muddy financially here in the US is a good thing.
a little data birdy said that ATT will be launching a series of netbooks before christmas and that tmo will be launching 1-2 netbooks after christmas.
also, i believe that this black sumtin sumtin is more data driven then some mobile phone. tmo has a really tiny sim device that data card developers can use which helps in the design of units. lets see if this comment stirs any pots or laughters?!

Due to a lack of service support on the Boost network, email and other data services were left out. Voice and (very) limited text only.

2. Yes Boost does have a $50 everything plan, but Boost Mobile only has the iDEN GSM/GPRS network with some very lacking dumb phones. There's no 3G, there isn't even a 2G, you get a max speed of about 19kb/s. If the unlimited everything includes a real internet plan with 3G and the possibility of 4G in the future AND the use of nice phones like Blackberrys and the N900, this *will* shake things up.

Yes, cpufreq handles the speedstepping. For users, there's absolutely no need to worry about any of this.
So? Unless you're transcoding video 24/7 there's almost no need for it to be at 600MHz at all times.
Damage to the silicon happens when the system is forced to run in overdrive mode (550&600) constantly, because of the extra voltage required by these operating points.
Tampering with these sort of settings puts the system out of its supported operating range.
Edit:
But normal usage is ok and only those who are planning to do 24/7 number crunching on their phone should be worried.

Now I experience a bug, for example in Flash (as I experience such bug on Linux desktop) which uses 100% CPU. On desktop I not even notice since the thing has more than enough resources (quad core etc).
Now my phone is in 500/600 range whole time, correct? Is this dangerous?

According to TI the OMAP3430 features the "TWL4030 is the optimized all-in-one audio and power manager" and "TI's SmartReflex™ power and performance management technology" which has "Sensors that adapt voltage dynamically in response to silicon processes and temperature variations." In any case, if this is built like regular CPU's it should have a temperature threshold, when this threshold is reached it should shut down to prevent any hardware damage.

After doing a little research, I discovered some things you guys might be interested in. I was curious as to why you guys kept mentioning 500mhz as a max when Wikipedia mentions 600mhz, so I started looking for links from TI to back up that speed. I found something perfectly fitting.
http://www.spinics.net/lists/linux-omap/msg13152.html
In adition to mention the max clock speed of the TI OMAP3430 as being 600mhz, I specifically love this part:
Looks like even if someone *was* doing full 24/7 number crunching at 600mhz that the CPU could hold up as long as it didn't overheat(which we can't guarantee)

Recently there was some change to also measure active time at max overdrive for same usage mix. This resulted in still meeting lifetime goals for typical usage.
This can translate to a smart phone maker of being able to use overdrive as they see fit and still have long life (assuming they can supply adequate power and still dissipate what ever additional heat there is). This is still not 100% of the time in active mode.

Which one of the components will fail first?
Ideally you don't want them to have too different lifetime and using the CPU locked in overdrive mode will definitely shorten its life.
Up to the point that, toward the end, it will not even function at lower voltages.
This doesn't apply to every unit, but we have to consider field failure rate and come up with margins that do not get it out of control.
Like in any other processor, some units support higher clocks at the same voltage, but we refer to nominal values.

If Project Black is a low cost plan, Wal Mart beat them to the punch http://www.prnewswire.com/news-relea...-64206872.html. This should pressure all carriers to be more competitive on price.

Even so, does anyone know if it would work with the N900?
All we can do is hope that our dreams of an inexpensive plan for the Geeks of the world is really in the works and soon to be in affect.
