This review is from: ARRIS SURFboard SB6141 8x4 DOCSIS 3.0 Cable Modem
Pros: Worked moderately well when it was functioning.* Supposedly good channel bonding and download capabilities.
Cons: NOT durable, NOT reliable, NOT a 5000 series workhorse. Failed within 9 months of ownership. Finicky about signal quality with Internet-only service, no couplings, no splitters, and no adjacent sources of inductive line noise.
Other Thoughts: I formerly had a SB5120 (Texas Instruments chipset) and SB5105 (Broadcom chipset) since 2005. They still function properly and receive download speeds on a single channel of up to 48Mbps (contrary to misinformation provided by Comcast) but do not have multiple channels for bonding (line/load leveling to benefit the ISP).
Last November, my ISP (Comcast) wrote me a series of letters advising me that service for the DOCSIS 2x series of Surfboards would be discontinued and that I had to procure a new 3x modem to continue service. Several phone calls to "customer service" verified this. My SB6141 was purchased in 12/05/2014 and failed on 8/27/2015.
When I started service at my current apartment (12/2013), the Comcast installer advised that my signal was so noise-saturated and over-attenuated that I could not run the modem through a surge suppressor. This was verified after multiple instances of tech diagnostic testing and visits to the modem's internal status page (192.168.100.0 I think). On a side note, it was verified that we were never able to get the 50Mbps we were paying for because the line topped out in the 18-24 range. Joy.
Meanwhile, being that we have substantial afternoon storms in North Florida, I suspect that the modem took an indirect hit through the coax cable line. Nothing else on the surge suppressor (or in the entire apartment) was damaged. After a phone call a field technician visited, assessed the line, determined that there was signal, and offered to SELL me a modem. Comcast has essentially refused to replace my modem that their lines likely damaged and I must now cancel all of their services and navigate the warranty repair process. Other than that, life is good.
* With properly sized cable and properly managed ISP
Pros: * reasonably fast I guess
* supposedly gets better mobile battery life
* boots Windows 7x64 Pro in about 20 seconds
* comes with a desktop conversion kit
* goes on sale for a halfway reasonable price about once a month w/ MIR
Cons: * makes a faint squealing noise when reading/writing ....???
* not noticeably faster than an Dell/OEM Toshiba 7200rpm drive
* only moves "large" files faster
* Made in China
Other Thoughts: Why does it make a squealing noise when reading or writing? It's not loud, but I can head it over the hum of the fan. Makes me glad I have a 5 year warranty and external backup drive because it may be a short-lived item.
SATA-2 limits usefulness of SSD's...I included an Intel 510 120GB SATA-3 in a new desktop build in 2011 that installed Windows 7 Pro in <10 seconds and boots it in ~5 seconds. The 320 series is *nowhere* near as fast.
Verify with Intel SSD Tools web page that you have the newest firmware so you don't get the 8MB wipeout.

This review is from: Symantec Norton Internet Security 2012 3 User
+ "best" virus and malware protection
+ comprehensive solution to internet protection
+ comes preprogrammed (could be useful if you don't know what you're doing and don't care what speed your computer runs at)
- takes over your computer & slows it down...a lot.
- can develop internal errors which cause your computer to stop responding
- the same errors also prevent laptop from entering sleep, restarting, or shutting down.
Other Thoughts: This Norton product was a free upgrade to my existing NIS security subscription via my ISP. I held off at first and then finally caved and allowed the "upgrade" to continue. With previous versions of NIS, you could put the software into "silent mode" once a day (but NOT permanently) to reduce the unnecessary average workload on your CPU (important for laptops on battery). The new version did not decrease the running processes or load when put into "silent mode."
I am running a Latitude e6400 with Centrino 2 P8700, 4GB RAM, and Win XPP_SP3. Plugging into A/C, docking it, closing all programs, etc. nothing fixed the failure to sleep/restart/shutdown issue unless the computer was opened in Safe mode (w/out NIS running) and then again after Norton was uninstalled. After uninstall, my system instantly became twice as fast.
This product from Symantec is junk and you should avoid it until they re-enable access to settings and make it a less CPU-intensive, more stable/ reliable product.
