Hang onto your wallets, cheeps, because I've got five -- count 'em, five -- deals lined up for your Friday.

Why the glut? Same as always: I found lots of really good items and couldn't decide which one to spotlight. Check 'em out:

1. One big TV. When it comes to bang for your TV buck, I think Vizio leads the pack. Especially when Vizio resellers serve up deals like this one: Dell Home has the Vizio E552VLE 55-inch smart LCD HDTV for $649.99 shipped (plus sales tax in some states). Although CNET had some nits to pick … Read more

Need a high-speed Internet connection to go from here to there? Stringing Ethernet cables through walls, floors, and ceilings is not my idea of a good time.

Fortunately, you can use the existing electrical wiring in your house. No, really! All you need is a couple plug-and-play wall adapters.

Usually they're pretty pricey, but not today: While supplies last, Newegg has the TP-Link TL-PA210KIT HomePlug AV Powerline Adapter Starter Kit for $29.99 shipped. That's after applying coupon code EMCXVVW262 at checkout. (As with most Newegg coupons, you need to be a newsletter subscriber to use this one. … Read more

Quick reminder: All prices, shipping charges, etc. are accurate at the time I write about them. They may (and often do) change suddenly and without notice. Frustrating, but true. Also, if a friend recommends a product and you get burned by the company, do you blame the friend? Remember, it's your responsibility to do your homework before buying from any seller; ResellerRatings is a great place to start.

Back in October I wrote about an inexpensive travel router that, much to everyone's chagrin, sold out very quickly. Here's hoping this one will last a little longer.

These days computing is practically synonymous with Internet access, and often in any given location you may have access to more than one network, be it Wi-Fi, Ethernet, or otherwise.

With multiple connections available it may be beneficial to prioritize the way OS X accesses these networks to ensure you use the desired one. For example, if you have a relatively slow Wi-Fi network in a workplace but also have a faster Ethernet network that can be used, when connected to the Ethernet port it would be nice to ensure OS X uses this connection instead of using Wi-Fi.

The increasing complexity of automotive systems, from diagnostic sensors to infotainment components, creates a need for more robust data networking. Two companies, Micrel and Marvell, recently announced a means of using Ethernet to address at least part of this issue.

Since the 1990s, cars have employed the CAN bus standard to send data between sensors and engine controllers. However, more airbags and the addition of safety technologies such as vehicle stability control tax the capabilities of the CAN bus standard's 1 megabit per second data rate.

To move forward, companies are looking at developing more robust networking capability in … Read more

Do you travel a lot? If so, you've probably encountered hotels that have weak or non-existent Wi-Fi, or that charge extra for it while offering Ethernet-based connectivity for free.

A good travel router can save the day, turning that laptop-only Ethernet connection into a Wi-Fi hot spot for all. For a limited time, and while supplies last, Mwave has the Powerlink PT-AP2403 mini travel router for $19.99 shipped. It sells elsewhere for as much as $35.

Update: Aaaand...sold out. Sigh. But it's worth checking back later in the day in case Mwave releases more inventory. Trying … Read more

Slow network speeds got you down? On Monday, computing experts will announce they're tackling the next speed bump for the venerable Ethernet standard.

But don't expect to find the new speed option on your next computer's feature list. The standard, to be produced by the Institute of Electrical and Electronics Engineers (IEEE), will likely reach data-transfer speeds between 400 gigabits per second and 1 terabit per second. For comparison, that latter speed would be enough to copy two-and-a-half full-length Blu-ray movies in a second.

In contrast, your laptop today probably maxes out at a mere 100 megabits … Read more

Apple has made available a small FAQ on its new Thunderbolt Ethernet adapter, which outlines some uses and limitations of the adapter, and also hints at potential troubleshooting for both it and other Thunderbolt devices.

In the FAQ, Apple makes particular note about the daisy-chaining of Thunderbolt devices; each chain can support up to eight devices (including the host computer). While in most cases users will have peripheral devices such as hard drives or I/O controllers attached to their systems, it is also possible to connect multiple computers in the same daisy chain (one use of this is for … Read more

We knew new MacBooks were on their way sooner or later, and anyone who held back to buy a new model (myself included) found themselves rewarded with an across-the-board set of updates.

I had my own wish list for what I wanted to see in the next MacBook, and surprisingly, many of my requests were met...in the Retina Display MacBook Pro.

Aside from that exciting and extremely expensive $2,199 machine, however, Apple's new lineup of MacBooks doesn't differ all that much from last year's lineup. Unless you want to spend north of $2,000, your Apple upgrade path for laptops involves choosing either an Air or a thicker Pro.

The future of Apple's MacBook Pros looks to reside in that newly designed Retina Display model, whether you like it or not. If that's the case -- and in the future these redesigned Pros become the core of Apple's product line -- here's what I'd want to see.… Read more
