Pros: Slim, Light, Rugged, Powerful. Wonderful high resolution screen, that is very bright. Firm keyboard, with good key layout - feels natural. Large responsive touchpad (I haven't had any of the issues that others here have mentioned). Long battery life (8+ hours).

Cons: OK, one minor quibble: the SD card slot isn't deep enough - a card will stick out from it when inserted, so can't be left in there semi-permanently for fear of it breaking off. But given the size of this machine this is forgivable.

Overall Review: I bought this last month at the Microsoft Store on special offer: $1000 for a Core i5, 4GB of RAM, 128GB SSD and 3200x1800 screen referenced here . This is absolutely the MacBook Air killer - same size and weight, but with a touch screen that is higher resolution. In the 4 weeks I've had this laptop I haven't found a thing wrong with it. The screen is beautiful and bright. The keyboard is firm and easy to use. The touchpad is large and responsive. The size and weight are superb, especially for a machine of this caliber. Everything feels like high-end quality on this machine. The "special function" keys are nicely laid out. I've had no problems with the WiFi around the house (both 2.4GHz and 5.0GHz). I spent a few hours upgrading to Windows 8.1 (it was supplied with 8.0), adding other Microsoft updates, installing other software (Google products, MS Office, many utilities, software development tools, and more) and personalizing it to my liking (screen resolutions, themes/backgrounds, power settings etc.). Also added Classic Shell to put the "Start" button (and menu) back where it should be. For general purpose portable use this machine is perfect.

Pros: + Small size + Good power CPU for this size + Decent memory expansion

Cons: - Expensive, especially compared to similarly specified laptops - only 3 USB ports, and they're not USB 3 - no discrete audio out - only available through HDMI

Overall Review: Given that it's necessary to add memory, a hard drive, and an operating system (typically a free Linux or Windows 7) to this unit, the final cost will be in the $500-$600 range, which is expensive, especially compared to similarly specified laptops (e.g. Core i3, 8GB RAM, 500GB drive) that also come with an LCD display and a battery. Although of course a laptop will have a larger footprint.

Pros: Small size - about 2/3 the size of a deck of playing cards. Terrific for traveling, especially since it comes with the travel bag. USB powered. Easy to use - I used it straight out of the box with no configuration/setup required. I left the default password in place, which is secure enough for now (8 alpha-numerics), and is included on a label on the bottom of the unit. WiFi is powerful enough for use throughout our 2200 SqFt house. We've used this with 3rd, 4th & 5th generation iPod Touch units, a Samsung tablet, a Kindle Fire HD tablet and a couple of HP laptops, and although it's not as powerful as our regular full-size router, it's good enough, and will certainly be powerful enough for any hotel room we're ever likely to stay in. Although it only comes with a 2-page quick start guide (which is good enough to get started), there is a 180 page comprehensive PDF manual available at ZyXel's site.

Cons: The travel bag is a nice touch, but it's not quite big enough to hold all 4 items: the router, the power adapter, the USB cable and the ethernet cable. I've kept the power adapter separate.

Overall Review: Great value - I got it on sale.

Pros: Easy to setup with Google Voice - instructions are included in the box - it took about 30 minutes maximum. Smaller than I thought it would be - it's about the size of a cigarette packet. The power adapter works on 120V & 240V, so great for international travel (with a cheap wired USA phone, that just plugs into the unit).

Cons: None. OK, it would be great if it could use a WiFi connection instead of a wired connection, but obviously that would cost more, and add complexity and (probably) size.

Overall Review: 2 weeks after buying this in early November, and setting it up, I visited the UK for a week. I used it extensively there (with a wired USA phone) at my father's house to call the USA for free. Every call was of high quality. So far this unit has exceeded my expectations. I hope Google Voice continue their free calling service in 2013.

Pros: Compact. 4 outlets. Can be used anywhere in the world. Blue light serves as a weak night light.

Cons: Slightly flimsy (only slightly), primarily where the international adapter plugs connect to the charging unit body. I suspect that after a few years of use they'll break somewhere in that area, but all of our units have been fine in that respect so far.

Overall Review: I have about 5 of these that I've bought over the last 3 years (usually in half price sales around 10 bucks), that my wife and 2 kids use all the time, both at home in the USA, and when traveling in the USA and Europe. We use them for charging a combination of: 6 iPod Touches (3rd, 4th, 5th gen - the kids have old & new models), a couple of compact cameras (Panasonic), a Samsung Galaxy Tab 2 7.0, older Sansa MP3 players, and most recently a Kindle Fire HD 8.9". These chargers will happily manage 3 or 4 of those devices at the same time, although I've noticed that if the Kindle Fire needs significant charging then the charger will get quite warm. We had one of these units fail about a year ago, after my kid took it to school for just one day. Since it had worked fine for about a year before that, and since all the other units have performed just fine, I'm attributing that particular failure to "someone at school must have broken it" (e.g. dropped it or shorted it out).
