Build and Design
Sony’s designers worked overtime to make the TZ not only an ultra portable notebook, but to make it an ultra portable notebook that looks good. Lines match up, panel thicknesses stay the same, hinges are molded into body with the battery, AC plug, and power button integrated, and it’s topped off with a carbon fiber lid to seal the deal. Lifting the display cover you find the glossy keyboard surface reflecting the world around you with keys standing out like ripples on a pond. This notebook could be perfectly described in one word; glamorous.
The build quality of this notebook is excellent. Having such thin panels merging together across various parts of the notebook you would almost expect to see uneven panel spacing or gaps, but this notebook has none. Panels merge together with razor thin clearances, and even flexing the notebook doesn’t make the parts squeak or groan from plastic rubbing together. Support is excellent around the base of the laptop, leaving just the screen with some amount of flex. I can’t really place too much blame on Sony for that, since it is only 4.75mm thick. Overall I found the Sony TZ to be of excellent quality, only lacking on allowing certain parts to be upgraded by the user.
Sporting a new LED backlight screen, a first for a Sony ultra-portable, the laptop is able to achieve great color reproduction and backlight distribution. Watching movies, editing pictures, or just browsing the web was very enjoyable. I only wish this laptop had the performance of a gaming machine, so that the screen could be used for more recreational purposes. Comfortable brightness levels on the TZ were around midrange, with anything above too bright for my poor eyes. As is common with most notebook displays, viewing angles were excellent horizontally, but poor vertically. The purple anti-glare screen coating combined with the poor viewing angles helped make dark colors invert at shallow angles.
Protection of the screen from the display cover is on the weak side, since it is extremely thin. Throughout the review procedure, the only damage I was able to inflict were key marks left on the screen from the LCD pressing on the dirty keys. These were only temporary marks, I was able to rub them off with a soft cloth (which Sony included with the notebook). Besides flexing the screen into a taco shape or accidentally sitting on it, I don’t see most users having any problem with the screen.
The speakers on the Sony TZ are located right below the pivot point of the display, providing a clear path to your head for maximum listening pleasure. They worked quite well for watching movies, playing games, or listening to some music around the office. With the volume set to max, the decibel meter registered ~64dB at one foot. The audio was only slightly distorting on high notes, but stayed mostly clear. During normal use high and upper midrange came through well, but don’t expect any lower notes from speakers this small.
Keyboard and Touchpad
The keyboard on the Sony TZ is very compact, and takes a bit to get used to typing on. It took a few hours of use before I could type without peaking at the keys. Passwords were mangled, friends were confused with my typing, and websites locked me out for too many login attempts. Once I got used to it the typing was fairly comfortable, but this keyboard is not ideal as a primary machine used during an entire work week. For users who would buy this machine as the main computer in their office, a docking station with full-size keyboard would be highly recommended.
The touchpad was easy to use, and very stable with finger tracking. It did not appear to have any lag moving across the screen, nor did it have any pause when it sat idle. My only complaint with the touchpad was the upper boundary was flush with the keyboard tray, making it easy to slide your finger right off the surface. The soft texture made the touchpad easy to control, as well as very comfortable on the fingertips.
Performance and Benchmarks
The only modern game I found to work at decent frame rates was Half Life 1 as mentioned in my first look. Watching movies, editing photos, and using productivity software worked out much better. The beautiful LED backlit screen really made those activities enjoyable. Below are the standard benchmarks to see how this laptop stacks up against others notebooks. Keep in mind that the TZ compares favorably to other notebooks in the ultra portable notebook class.

Once you dig deep past the bountiful bloatware, and get a chance to uninstall most of it, the TZ really becomes different machine. Power usage drops, programs load faster, startups and shutdowns speed up … I can’t recommend enough that users clean off all of the bloatware before they start using the notebook. If you add up all the preinstalled software, by far the most has to do with specific Sony notebook features like backlight adjustment or eject functions. If you take off too many, you start to lose vital functions. I really wish Sony incorporated all system functions into one software package.
Under normal use, backlight at 80 percent, Sony Optimized power profile set, and using wireless for web browsing, the TZ pulled off six hours and 43 minutes. I was hoping for more, as the preproduction model seemed to go more than seven hours, but it was still very good. Watching movies on the laptop got just less than four hours, meaning you could get through even the longest movies on a flight without a recharge.
Charging the battery took quite long compared to what I have been used to. More than five hours to get a complete charge was not out of the question, and two hours to get over 50 percent. Most other laptops will charge at a faster rate up to the 75-80 percent level, but the TZ had no such feature.
Heat and Noise
Even with the low voltage processor and SSD drive, the Sony TZ could produce heat with the best of them. The bottom of the notebook got quite hot even under normal use, and the fan was always running after the notebook had been on for over 20-30 minutes. Fan noise was minimal, and the only way to tell it was blowing would be sticking your hand next to the outlet, and feeling the warm air blow past.
Below are heat overlay images showing where the Sony warmed up (in degrees Fahrenheit) during normal extended use.
Compared against every other ultra portable notebook I have worked with, the Sony TZ was by far the brightest, lightest, and smallest of the bunch. The screen was gourgeous, battery life was excellent, and the notebook barely weighed anything. I would recommend this notebook to anything considering a portable laptop, especially those who demand the lightest possible items for travel.
- Amazing LED backlit screen
- Almost seven hours of battery life
- SSD Hard Drive
- Bottom gets very hot, pants required.
