I purchased this item almost 8 weeks ago 8 August 2014 will i receive this item in my lifetime or will i need to leave this item in my will for my kid

Purchased SB6183 a week ago, My invoice says estimated shipping between Oct 1 to 10th. What was your estimate date? If i don't see any update by Oct5th i'm going to cancel my order and stick with SB6141.

Does ARRIS/Motorola support firmware upgrades for the 6183 via downloads to the consumer's computer? If not, why not?

If there are upgrades, you will be able to download, as you would for any piece of computer hardware. The cable companies do NOT have any control over what you download or what modem you use. It may not work if it's not using the right protocols, but they aren't going to exclude any that do work. And just about ANY gateway/router hardware will work. Again, the cable company has no control whatsoever over what router/firewall you are using.

What is the difference between this modem, the SB6183, and the SB6180?

The SB6180 enables channel bonding of up to 8 downstream channels and 4 upstream channels, which allows an operator to offer their customers advanced multimedia services with data rates of well over 300 Mbps in DOCSIS mode and 400 Mbps in EuroDOCSIS mode for downstream and 120 Mbps upstream. The SB6183 has 16 download & 4 upload channels. Download speeds up to 686 Mbps and upload speeds up to 131 Mbps based on your Cable provider service. That is the main difference I could find. I hope it helps.

do most users need such a fast cable modem? I have comcast performance....is this over kill or futureproofing with docis 3.1 on horizaen.

DOCSIS 3.1 is here, true. And the first set of cable modems using the standard will offer some improvements. As with many technologies, they don't saturate the market overnight. In most cases the availability and maturity of a technology in the marketplace can take years - as much as 3 to 5 years. Even if 15 to 20 percent of the market goes to DOCSIS 3.1 in the first or second year, that says 80 percent hasn't. Future proofing your technology is nice, but a measure of sensibility should be used too. I went to the ARRIS SB6183 knowing that my ISP service is 200 Mbps. It allows a considerable cushion for growth. If my ISP's average speeds jumped to 500 Mbps, and I were to consider another cable modem upgrade, I would focus on a faster cable modem that uses the DOCSIS 3.1 standard or any newer and more powerful standard - allowing me to benefit from the latest standards and speeds. The DOCSIS 3.0 standard may well be nearing its End-of-Life in 2 to 3 years. Therefore, I would see no value going to a 1.4 Gbps DOCSIS 3.0 modem.
