Actually, when Qualcomm was first developing EVDO they had a unit that had ethernet, a DHCP server, and a router with NAT. It was nicknamed "Hornet" This was a very cool device but was very expensive. I'm sure the cost is the primary reason we don't see more devices that do this.
The piece that many of you are missing on thier pricing scheme are the recurring costs associated with these data services. In order to support EVDO the carrier needs to add additional T1s to each cell site (usually two T1s per cell). When you multiply this by the number of cell sites a carrier has, the cost is quite high. Also, this system is completely different than the existing voice, and for the most part data, systems that are already in their offices. So, they have had to upgrade their network infrastructure and send a huge number of their employees to training.
I'm not saying that the current pricing accurately reflects the true cost to the carriers for these services. I'm sure that in the future we will see these cost continue to fall, we have already seen Verizon go from $80 to $60. What I am saying is that many of you do not realize what it costs a provider to keep a network like this going.
This is certainly not the same as allowing someone to copy a commercially produced recording but there are a lot of bands that allow the trading of their live recordings. For a list of these bands see http://btat.wagnerone.com
Also, as someone else has already mentioned, etree.org and furthurnet.com are great resources for this material.
This has been discussed here several times before. See this article and this one.
By the way, I have been installing these networks for Sprint, Verizon and a few other smaller service providers for about the last year. So, of course I have tested them dozens of times. The actual throughput is usually about 8-9KB/s. In an area where the signal is strong and the cell does not have a whole lot of other traffic these rates go up to more like 11-12KB/s. The amount of traffic on a cell will impact these speeds because the burst rate is negotiated between the switch, cell and CPE and depends on the amount of data being transfered and the available resources on the cell. Bursts typically last about 5 seconds and then have to be negotiated again. So, this system can use a lot of resources but will only use them when they are available.
Also, this is 3G. See the articles I just mentioned for a lot more info.

I travel almost constantly and have tried Bose and Sony noise cancelling headphones. I recomend the Bose. They are quite a bit more money but in my opinion are well worth it. I don't leave home without them.
1XEV is still being tested in our labs. We expect to start selling it to our customers in about 3-4 months and it will probably be at least 6 months after that before end users will have the service available to them. That is if 1XEV takes off like we hope it will.
I work for Lucent and have been deploying this technology for companies such as Verizon and Sprint for the last few months. The technology Verizon is announcing is known as 3G-1XRTT. There is another 3G technology, 3G-1XEV-DO, which will be available soon. 3G-1XRTT supports speeds up to 144kbps. 3G-1XEV increases this to 2.4gig. The way that 1XRTT actually works is that each user gets one 9.6kbps channel when they connect. Then, when the user is transfering data, the cell site or the handset can request to "burst." The speed at which you burst depends on how much data you're transferring and how many resources are available on the cell. This burst speed can be any multiple of 9.6 up to 144kbps. Bursts only last for a few seconds (typically 5 or less). After that the cell/handset have to negotiate another burst. This is because as you might imagine, this can use a lot of resources on the cell/switch. For this reason, if you are not transfering any data for a few seconds, your call will go into a dormancy state. This means that all of the resources on the cell are released and your airlink is dropped. However, the call is still registered on the switch. So, when you go to transfer more data, the call comes back up and you don't have to be authenticated again or reregistered on the switch. It's a very cool system that can use a lot of resources but only when it really needs them.
I'm sure you're all wondering what kind of throughput you can really expect to see from this. In my tests I typically see rates of about 11-12KBps. You may not see speeds quite that good in an area where a lot of people are using wireless services but I'd expect most people to see speeds about that fast. It's not as fast as cable or DSL but it's at least twice the speed of a 56K dailup - pretty darn fast for a wireless phone.
I speak for myself and not for Lucent.
This is absolutely correct. AT&T has great coverage and it looks like Verizon should be good as well. I have the AT&T 1 rate plan. I am constantly travelling all over North America and I am very happy with the service. Many of my friends and people I work with have service from CellOne or SprintPCS. They often do not have service when I do but I always seem to have service when they do. Also, the 1 rate plan is great for people who travel a lot because there are never roaming charges if you are w/in the U.S.

Ooops.. I didn't think I'd hit submit before my browser crashed so I posted this again. **mubled curses about IE**

Have you looked at Disc Backup - http://discbackup.home.dhs.org/ ?
I haven't tried it yet so I can't vouch for it but I downloaded it a while ago and it claims to do backups across multiple disks.
