Very unlikely anything needs 5 volts other than the USB connector assuming it is a HOST connector for mice, keyboards, etc. But even then the 5 volt port will not need a tightly regulated 5 volts, it just needs to be within the input spec... which is somewhat tight at
4.75 to 5.5 volts typically. But to be sure you would need to check the data sheets for the parts in question. Since there is no schematic available currently, can't do that.
Considering cell phone batteries typically have a capacity of 1000mAh or more, at that rate it would take more than 8 weeks to fully charge it. I guess you are a very, very patient guy ;-)
Um, not. That is the GUI/DE that eats all that RAM. The actual functionality is maybe 5 to 10 % of that. Basic running interactively, with a file system was done in 16 K on a 6502. You have heard of bloatware.
Hmm, strangely enough there was a link in another thread here where the main guys from Olimex were trashing the R-pi a bit and doubting they could make it for the price.
Do you think they have an ulterior motive and not exactly unbiased position?
Are you using the Hollywood edition of C++ with Gibson extensions enabled? (Usually installed under the name 'Java'.)
Memory usage while compiling KDE4 C++ sources from the command line:
PID USERNAME PRI NICE SIZE RES STATE TIME WCPU CPU COMMAND 1333 root 25 0 332M 316M CPU/0 0:17 96.03% 57.03% cc1plus 1351 root 85 0 48M 32M pager_/4 0:00 2.47% 1.46% as
316MB in use by the compiler. C++ is Peeeg. And then there's Java, which is Mrs Peeeeg after 8 years of marriage..
And it was said this proposed supercheap 64MB RAM RaspberryPi killer would run Android and its Java systems. Uh, you need at least 768MB of RAM for Android to be usable at all.
You need to put significant effort into getting that information out to the right people, convincing the sales channel that this is the right thing to push as well as the media.
Then get 10000 people to commit to buying before delivery
Anyone who can do that needs to put in a lot of effort.
Not delivering - well that is easy. Keeping momentum and recovering from it could be challenging.
I'm just not so sure why so many people appear to want them to fail.
So to do any programming of the RPi, you still need a PC with Linux either native or in a virtual machine. Of course the same is true of any other low-cost system.
It does seem disingenuous to promote the idea that you could do significant hardware and C software development with the RPi and just a keyboard, monitor and mouse. You really need a PC and a second keyboard, monitor and mouse unless you plan to switch a lot of cables when you want to test your software.
Compiling KDE is a pretty extreme example. I find it rather disingenuous to dismiss the device as unfit for any purpose just because it isn't everything for everyone, especially when the complaints are about things that weren't design goals in the first place.
That would be faster but you don't need an extra keyboard and monitor. You can work remote from a Linux system. Mount the filesystem of the RP using fuse and have the RP use the Linux system as X server for output.

Failure does not prove something is impossible, failure simply
indicates you are not using the right tools...

And that shirt still hasn't been ironed. No product, no win; good = product (even subsidized by Broadcom, funny situation - did they order too many millions/) possible big win. Result not known yet.
And that is supposed to mean something? It is a sloppy engineer that cannot beat off such sloppy bean counters questions, and has a sloppy manager for letting the bean counter get to him/her with sloppy = questions.
