TabletKiosk Sahara i440D Slate Tablet PC First Look Review

by Reads (9,768)

TabletKiosk recently introduced their newest Sahara Slate PC, the i440D and guess who got their hands on one. That is right, the i440D is in the office and our model is running Vista. After spending a few hours with the i440D, I was quite impressed by how fast the wireless connection was and how responsive the pen was. Key factors to look for in a slate tablet considering it has no keyboard and probably will be lugged all over the place.

Design and Build

The i440D Slate Tablet PC has a solid chassis. The model I am reviewing has a black housing with a nice rubber-like matting around the screen, which gives it grip. It feels similar to the grip on the newer smartphones like the Palm Treo 755p. The i440D is also available in white, but I am sure the black model hides dirt better.

I had no problems carrying the tablet around for long periods of time either, but it only weighs around 3.3lbs. That is why it is targeted toward the vertical markets, not that it isn’t a good tablet for normal users. Considering it is so easy to carry around, it would be great for note-taking and presentations. It even has a presentation mode in the control panel under Tablet PC settings, where you can also change display, battery status/performance, screen orientation, wireless settings and external display set-up.


It is powered by a 1.83GHz Intel Core Duo LV L2500 processor, which does a fine job surfing the Internet and even running some of the benchmarks. I mean this tablet isn’t meant to be a replacement for your notebook, but more of a niche market model.

In the below results of Super Pi, where the processor is timed in calculating Pi to 2 million digits:

The i440D has a 12.1" XGA (1024×768) display that has a dual mode active digitizer and touchscreen, which can be changed at the push of a button. The display is nice, it doesn’t have much of a glare, but it is a little washed out especially if you don’t adjust the brightness setting to 100 percent. It also has three programmable buttons along the side of the screen that the user can can program to their liking.

First Thoughts

There is a nice array of features on the i440D and it can be connected to a dock or you can use the included stand and connect a mouse and keyboard. Even though it is different not having a keyboard, the pen works great and is accurate. Overall the Sahara i440D seems to be a strong tablet with good battery life, but I need some more time to dive into those tests. Stay tuned next week for the complete review to come with video.

There is no ports on the right side or bottom, so basically what you see is what you get with the i440D. There are a few switches on the top, which are pictured below and a few programmable buttons next to the screen.
