Users looking to upgrade internal components shouldn't have any problem getting to the system memory or hard drive as long as they have a good set of precision screwdrivers. The Toshiba Satellite T135 is unique in that it uses Torx screws for the hard drive plate ... which aren't always kept in the average person's arsenal of tools. The memory slot cover used standard Phillips screws, so that can be opened even with very common tools. No warranty void if removed stickers were found anywhere, so it should be safe to swap out components without risking your support contract.
The 13.3" LED-backlit screen rates about average compared to other similarly sized screens. Color saturation appears to be above average, but the weaker contrast ratio doesn't help with really deep black backgrounds. Viewing angles rate slightly below average, with colors quickly inverting both vertically and horizontally. Vertical viewing angles start to show color inversion about 15 degrees forward or back. Horizontal viewing angles start to show color distortion at about 45 degrees, mostly in the darker colors. Viewing brightness is adequate for viewing in bright conditions, but outdoor visibility is limited from the amount of reflections off the panel surface.
Keyboard and Touchpad
The full-size keyboard is comfortable to type on and offers excellent support even under very strong pressure. I found the palmrest size to be just perfect to rest my wrists without causing any stress points while typing. The individual keys had a reasonable springy action and, while not as stiff as other keyboard, is still very responsive. Each key had a non-cupped flat surface, similar to a Chiclet-style keyboard but without the sharp drop-off between each key. Typing noise was minimal, with very little sound emitted when each key was triggered. Consumers who are thinking about buying this notebook for typing long documents should have no problems whatsoever.
The Synaptics touchpad was a slight disappointment in that it had a very slow refresh rate. Compared to other touchpads where you can draw circles quick enough to the point where the cursor starts to test the refresh rate of the panel, this particular version reminded us of those old mouse trails. Replacing the drivers with the latest ones offered on the Synaptics website was of no use, since it exhibited the same problem with those as well. The good news though is with the drivers uninstalled, the slow refresh speeds were gone, meaning that it is entirely a driver problem. Going without the drivers isn't the best option for most uses though, since you lose helpful features like scrolling, and corrective features that equalize movement on the X and Y axis. Not counting the driver problems, the touchpad wasn't that bad to use with a great surface texture that allowed you to glide your fingertip effortlessly across the surface. The touchpad buttons could have been improved, as they are part of a single span that pivots at the center. If you normally center your finger by feel alone, you might accidentally click on the middle (which doesn't move) or click on the wrong side.
Ports and Features
Port selection is fairly good when compared to ultraportable notebooks, but without an ExpressCard slot it is lacking compared to regular notebooks. The T135 includes three USB ports, VGA and HDMI-out, LAN, audio jacks, and a Kensington Lock slot. Expansion slots include just the 6-in-1 SDHC-compatible card reader.
