The projector isn't particularly bright at 15 lumens, so you'll want to make sure that you are in a well-darkened family or conference room before switching it on. Once it's on, you can use the projector to show your Keynote presentations, movies, or slideshows to anyone in the room. The device projects images up to 50" diagonal, so it's almost like having a big flat-screen TV in your pocket.
I was able to use the projector for about two hours before it shut down. The battery still seemed to have some juice in it as I was able to turn the projector back on in a while, but it appeared that the shutdown was due to overheating. There is no way to run the projector from an AC adapter, so you are definitely tied to the life of the non-replaceable battery.
There's a focus adjustment for making sure that the image is sharp, and there's even a built-in .5 Watt speaker to supply sound. Frankly, you'll want a Bluetooth speaker like one of the Big Blue models I'll talk about later in this review.
I watched some short segments of movies, some presentations, and a slideshow or two using the Pocket Projector, and for the most part I was happy with the results. However, this isn't a replacement for a much more capable projector for one very big reason -- the native resolution of the device is only 640 x 360 pixels.
While the images seemed fairly sharp and colors were bright, small text suffered. However, as you can see from some of the photos included with this review, screen text was very easy to read so your mileage may vary.
I think the best use for this device would be for showing images; giving slide shows to friends or clients, watching home videos or product videos. It's definitely doesn't have high enough resolution to be used as a projector for classes or meetings, but still a fun and useful product in the right use cases.
Big Blue Studio and Live Speakers
We get a lot of Bluetooth speakers here at the TUAW Labs, some of which are high-end units and others that are cheap. The Big Blue line seems to hit the middle ground, with a big speaker that's more reasonably-priced than some smaller devices like the Jawbone Jambox.
The Studio Speaker comes in a white polycarbonate shell with a metal grid covering the front, dominated by a big blue "eye." There's a hefty looking AC adapter with a thin cable that powers the unit. The speaker has a total 30 Watt output, with two full-range 2.5" drivers, a 3" subwoofer driver, and a passive radiator. The Studio Speaker supports any Bluetooth 2.0 or higher device with A2DP, GAVDP, or IOP compatibility.
