Both devices run on Android v1.6 Donut, have 3.2 megapixel snappers, ST Ericsson 416MHz processors, 256MB RAM, 512MB ROM, and full connectivity package – Wi-Fi, 3G, GPS, Bluetooth, FM radio and 3.5mm audio jack. The common specs sheets end with an accelerometer for auto-rotate and a microSD card slot.

Acer beTouch E120 sports 2.8-inch QVGA touchscreen, while beTouch E130 uses 2.6-inch landscape QVGA touchscreen and full-QWERTY keyboard below it. The QWERTY bar form factor is definitely a novelty in the Android world.

We are already familiar with E130, since it was recently showcased at Computex 2010.

Both beTouch devices run on Android OS v1.6 Donut and will feature additional software such as Acer Spinlets (for accessing or sharing media content) and UrFooz (for social networking).

Both phones will be released in Q3 this year in black and white versions. Acer beTouch E120 will hit the shelves in mid-July, while its QWERTY sibling E130 is expected in August. There is no word on pricing yet.

Let’s see what we have here – a 3.7-inch AMOLED touchscreen with 480×800 pixels resolution, the 1GHz Snapdragon and 512MB RAM put it on par with the Nexus One so far. But the Acer Stream also carries 2GB of built-in memory (8GB card included) in it’s 11.2mm thin package.

The list goes on – H.264, XviD and WMV HD codecs are supported and there’s an HDMI port and DLNA plus UPnP, to get the images and videos from the Acer Stream to your TV. Speaking of images and videos, the Stream is equipped with a 5MP camera that can capture 720p video and the GPS receiver enables geo-tagging.

Connectivity is rounded off by Bluetooth, Wi-Fi 802.11n and 7.2Mbps HSDPA. And if the media capabilities of the Acer Stream didn’t seem like enough, it also includes Dolby Mobile technology.

The Acer Stream runs Android 2.1 Eclair with custom Acer interface on top. They’ve built social networking and free music streaming services into it along with other things.

The Stream is built out of sturdy, resistant materials but that comes at a price – 140 grams of weight. It seems hefty, but the Nexus One weighs in at 130 grams, so it was to be expected.

Since the Acer Stream just became official, we don’t know details like target availability date or expected price.

And while we know a few bits and pieces about the I5801 and I550, there’s hardly anything we know about the touchscreen equipped smartphone Liquid Stream, except for the fact that it runs the Android OS.

As for the I5801 and I5500, they have already made their first public appearances… a few times. The Samsung I5801 (a.k.a. Galaxy 3) comes with a TouchWIZ-ed Eclair in the pocket as well as a GPS receiver, microSD card slot, 3.5mm audio jack and support for Wi-Fi and Bluetooth. It also features a 3-megapixel snapper able to shoot QVGA videos.

The I5500 is said to be part of the Corby family and to be based on the Android v2.1 too. It should pack Wi-Fi and Bluetooth support as well and to have a GPS receiver on board. The I5500 is expected to sell for around 200 euro which sounds like a fair price for an Android-powered device sporting all those features.

There is still no information of the expected availability and price of the other two.
