You only did half a review there...
.....so you got to the bit where you can install the Modaco custom rom, but didn't really explain any of the benefits. I have an Advent Vega, and went in eyes open that a little bit of time with the device and I'd have a properly flexible tablet.
With the Modaco rom you can enable the (fullsize) USB port in host mode: the benefits are numerous. Plug in any old USB key to transfer and view files - check. Plug in a mouse/keyboard - check. Plug in and surf using a 3G dongle - check. Options for expanding the memory - SDHC card and USB storage. Options for extending the iPad memory - err, buy another iPad?
All the usual consideration about openness of Android v walled Apple approach. Example: I can easily swap video content from laptop to desktop to tablet with no need for recoding and formatting, it just works.
Granted the screen isn't going to blow your mind, but it is more than good enough. The underlying hardware is futureproofed for Honeycomb. I chose the form factor BECAUSE it was 16:9, for me, video on the iPad is a bit old-school, with its letterboxing of widescreen footage.
I could not justify spending the massive fines that Apple imposed on the iPad, and nor did I want to. My use case suits the Vega, and so did the price. I would therefore change the scores as follows:
Review based on people who want a cheaper ipad: 65%
Review based on people who can operate a PC and want a decent Android tablet: 85%. (loses points for screen quality).
