Sony promises 8 hours of battery life, not amazing but I've found it to be pretty accurate. It can take up to 3 hours to charge fully. Some people say some Turtle Beach headsets get around 15 hours on a single charge, but I like having the official headphones.

If you want to listen to your music through your PC or Mac, looks like it'll work.

"The gold headset comes with a wireless USB dongle that works not only with your PS4, it also with any PC or Mac computer."

For the new Razor Blade (with NVIDIA 870M video card), there is a link to Amazon on the product page, where it says you can "pre-order" it: http://www.engadget.com/products/razer/blade/4th-gen/?buy

I went on the Razor's official site and you can order it now, but there is a back order and will be "Available to ship in 3-4 weeks": http://www.razerzone.com/store/razer-blade

What about Stay app? http://cordlessdog.com/stay/

I think you can creat multiple desktop arrangements, create one for multi-monitor and one for single desktop.

I had been also looking for a good wireless headset, I had the Razer Chimaera wireless headset for the xbox 360 and was blown away at how good a game with good audio engineering in it (Battlefield 3) could sound, but they're not compatible with the ps4 so I'm on the hunt for a new headset as well.

This is another great thread I found on reddit, from when when everyone was trying to figure out what ps3 headsets still worked with the ps4: http://www.reddit.com/r/PS4/comments/1qtizq/america_can_we_get_a_list_of_working_headsets/

Iphone Headset Doesn't Work
I tried the Apple's iphone headset, and it seemed like it might satisfy me till I got a legit pair, but like people in the reddit article mention, they cause a high pitch sound though the mic (you can see what I mean if you record a voice message and play it back).

PS Vita Headphones Are Probably Not What Your Looking For
Although I'm sure they're great for casual gamers, much like if the iphone headphones even worked, I don't think these are going to give you the 5.1 or 7.1 surround sound quality you're looking for for games like BF4.

Tritton Kunai - Wired Headset For $50
If you're not looking for a wireless headset I'd do these, the ps4 version of this headset was on for $50 (select "for PS4" in the dropdown here: http://www.engadget.com/products/tritton/kunai/specs/).

Logitech g930 Way Too Quiet (Avoid these!)
I bought thet Logitech g930's on Black Friday because they were on for $69 (reg $120) and people in the comments said they worked with ps4 as well, but I returned them because they were way too quiet, even at max volume, it was a waste of time, I'm sure they work great on PC, don't buy these for the ps4.

Astro A40's Too Expensive
The Astro A40's seem to be a very popular choice, however they are not wireless, $240 for non-wireless headphones? I'd spend the extra $50 to get the wireless ones for $299 but that's only $100 less than what I paid for the entire console, it seems crazy to pay that much!

Turtle Beach
A lot of people swear by them and only buy Turtle Beach, you can find a list of compatible ones here (http://www.turtlebeach.com/console-compatibility) but do some reading if you have to buy one of their new compatibility cables for yours to work.

Playstation Pulse Elite - What I'm Holding Out For
Wireless headphones for under $125, and by the company that makes the console? I'm in! However, they aren't supported yet, Sony says they need to push out a patch for them to work with the console in early January, so I'm holding out for when and if they actually do that.

SoundCloud, different genre than Spotify/Rdio, but it seems like every music blog uses SoundCloud to embed songs now.

The Delta Six controller Kickstarter is over (http://www.kickstarter.com/projects/356540105/delta-six-a-new-kind-of-game-controller), but you can now pre-order it on the official site for $240 https://www.thedeltasix.com/preorder/ . Near the end of July their twitter account said they hoped to ship them in time for xmas this year.

Amazon Kindle Fire is kind of the definition of a budget 7" Android tablet made for media consumption (as long as your into Amazon services), for $199: http://gdgt.com/amazon/kindle/fire/If you not into the Amazon eco-system I'd probably pay the extra $50 for the better specs on the Galaxy Tab 2 suggested above. The BlackBerry Playbook also fals into this price range, but it's not Android.Comparison: http://gdgt.com/compare/tablets/69953+25974+73807/

I use PdaNet everyday on the train into work. I use a Droid X so I'm on 3G, so the speeds aren't amazing, but I'm still able to get quite a bit done. The battery usage is tolerable (moderate usage, maybe 10-15% drain after 45 minutes). If you had a 4G phone it would probably be better speeds, but I assume more battery drain as well. Mobile hotspot devices can be a little bit more convenient though; no usb cable connection needed.

The only real difference between them announced as of yet is the screen size; 4.6 in on the Ion and 4.3 on the S. Ion comes with 16gb, S comes in both 16gb and 32gb. I personally really like the design of the Xperia S better.

Only carrier announced for the Ion is AT&T, no US carriers for the S have been announced but it will be available on "Three UK" in the UK.

I've been using Google Music to manage the music on my phone. I prefer to have them stored on the phone since I have lots of space and would prefer to save the battery from streaming them, so any music I add to Google Music I add to a playlist I have marked as "Offline" in the Google Music app.

I kind of assumed not all Android apps would be on the Fire simply because not all the apps that are in the Android Market are in the Amazon App Store. Would like to hear more about these APIs Amazon is blocking though.

Walmart has their black friday deals up now: http://localad.walmart.com/Walmart/new_user_entry.aspx?forceview=y&promotioncode=LA_Walmart-111121A

I quite enjoyed my Jawbone so I'd recommend a Aliph headset; small, minimal, subtle look. Also includes their patented noise cancelling technology Noise Assassin.The latest model, the ICON HD, is only $99. Or the Jawbone ERA (http://gdgt.com/aliph/jawbone/era/) is on sale for $99 on amazon (regular $129).
