Well, maybe the problem is that the project initially was too ambitious for a small company. I remember when EOMA-68 would be sold in stores and you could put it on any kind of device. It was a very good idea, but very difficult to do (at least without the money of a big company). The problem is that people will be reluctant to buy a computer with Allwinner A20. Even the people will be reluctant to buy a computer without Windows or Linux (x86). Perhaps it would be interesting to establish requirements for software and minimum hardware requirements as did 96boards. > > And ultimately a 2G RAM laptop is 'toy' these days, > > because 'browsers'. > > *sigh* tell me about it... bear in mind this is only a 1366x768 LCD. > > > So I was waiting to see if the upgradability > > aspect looked likely to actually solve this issue, and I have a pile > > of other half-started projects so don't _actually_ need any more :-) > > > haha > > > So, er.
