ViewPhone 4e
Another fringe smartphone manufacturer, ViewSonic, continued their attack on the dual-SIM market at this year's Mobile World Congress in addition to showing off some new tablets. The ViewPhone 4e and 4s are both disctinctly mid-range phones, while the higher-end model, the 5e, wasn't on display. The 4e runs Android 2.3 Gingerbread with plans of an update to ICS shortly, and is powered by a modest 650 MHz processor and 512 MB of RAM. One the back it's packing a 3 megapixel fixed-focus camera while the front constitutes a sad little 3.5-inch 480 x 320 touchscreen. "Affordable" is going to be the key word when thinking about this one. The 4e will be hitting Europe in Q2.
Climbing up the food chain is ViewPhone 4s. It runs ICS, and has a 1 GHz processor with 512 MB of RAM, and while the display is also 3.5 inches, the resolution is bumped up to 960 x 640. The camera on the back clocks in at 5 megapixels with flash and autofocus, plus it's accompanied by a secondary video camera on the front. It'll be launching in June in Europe. 
The ViewPhone 4e and ViewPhone 4s both have much more interesting designs than the phone ViewSonic launched at the last MWC, but if there's one common thread since last year, it's buggy software. I don't know if these guys are just showing off their products too early, but trying to type on the entry level device off-camera was tricky since the UI was in a perpetual carrousel; the screen would just drift lazily to the left and wrap around the right side in mid-operation. 
 Good on ViewSonic for tackling the dual-SIM niche, but I'd really like to seem them stabilize their software before showing it off. Besides that, anyone taking bets on how long until Apple sues these guys into the ground for using the 4s name?
