Enso, maker of the zenPad, have just announced 3 new Android tablets with 5", 7", and 10" screens. ( They also now have a couple of Android phones and a Mifi unit, but I'm going to pass on them.)
The zenPad 2 has a 5" screen and runs v1.5 (an upgrade to v2.1 is coming soon). It's running on a 624MHz CPU, and has 3G, Wifi, GPS, an accelerometer, 256Flash and comes with an 8GB microSD card (up to 32 GB supported). Enso are selling it for $219.
I'm not so sure this is worth buying. Very little software runs on v1.5 (most require v1.6 at a minimum), and a 624MHz CPU doesn't meet the requirement for v2.1 (min 1GHz).
The zenPad 3 has much the same specs as the zenPad 2 only with a 7" screen, not 5" . Enso are selling it for $249. Again, I'm not so sure this one is worth buying. Based on the Android tablets I've seen, I think a 624MHz CPU is underpowered.
The zenPad 4, on the other hand, is making me drool. It's based on a 10" screen and runs v2.1 on a 1GHz CPU. It doesn't have 3G, but it does have Wifi, 2GB Flash, a microphone, a 8GB microSD card and an accelerometer.This one strikes me as a much better piece of hardware. You can buy it from Enso for $199. (Did you notice that it costs less than the other 2?)
