Well, on wikipedia it says that most commercial products buanrantee a 1 million rewrite cycle, although I remember reading a few months back, that the cheaper brands (of USBs) tend to have higher failure rates, and the good brands have about 500,000 rewrites. But maybe it's changed now, and the number's gone up to 1 million

the cheapest usb memory often fails after a few thousand writes only. However that's the ultra cheap stuff - anything with a brand name should be safe to buy.
But if you want to use flash memory in place of a computer's hard drives then you will need many times more than a million write cycles over the life of the computer. Flash memory just won't cut it for that kind of use (yet).

oh what will the futur bring ahy? there already looking into 128bit systems  we got our dual cores our 64bit dual cores but people still use XP 32bit loltbh should hult production on CPU's for now there are 2 many sockets andbrads out now miss the old ways (of socket 7 and slot 1 and socket 370 ) to people with a life thats
socket 7 - Pentium 1
slot 1/2 - P2/P3
Socket 370 - P4 and very early P4
then we got
Socket A and 478 - P4/AMD Athlon XP/semprons
754/755 AMD 64 athlon (upto 3300+)
939/940 - 64bit athlon (3400+ - 4000+)
and from there on in i dunno we get a new MB range of sockets it seems like once every say 4 months...
anyway
should stop develop ment on FSB's - Ghz and general CPU's and focus on SATA/II with all its overheating CPU problems, get the FSB actulery running at 800mhz not at a physical 555mhz (this is due to RAM, SOuthbrridges and all that crap) and ge flash running to slowly take over HDD's and llow the noise spinning mass storage information super store relax and take a nice retiarment like FDD's/ZIP100/400 when USB flash hit it big...
thats my view anyway

hard drives are still the only reliable long term storage format for computers. Flash memory based pc's are still a long way off.

Although I think either Samsung or Toshiba, or someone either released or made a prototype of a lapotop with a 20 or 40GB worth of flash memory. Yes I know the deatail are a little sketchy, but at least I've got it out

Yes, we'll start to see examples coming out, but I don't think you'll see flash memory replace hard drives enmasse for a long time yet.
Samsung had a flash based laptop at cebit this year. But in reality it was a normal laptop with Samsungs 32GB flash memory in the hdd slot. Yes it'll work, but what's the durability? Computers write to the hard drive many thousands of times a minute sometimes. For example the swap file. You have to redesign the way the swap file is saved to "disc" (in this case flash memory) otherwise you'll get a dead spot very quickly where the swap file is stored in flash memory. There are other examples.
Samsungs effort was a demonstration of their flash capacity of 32GB, not a demonstration of a flash based laptop as such.

The annoying thing with flash memory is the constantly changing formats. MS PRO Duo can go up to 32GB but would Sony produce it, because by that time it won't be used by many/any devices. So, it's M2 that has gone back to square one and is now on 1GB and soon 2GB.
The constant desire to reduce the card format isn't helping reduce costs surely.
