I just got an email for the latest Fujitsu Slate, a continuation of their long running line of tablets and convertables. While not directly an Android or iOS competitor, the Win7pro OS gives you full functionality and they still claim 8 hour battery life.http://store.shopfujitsu.com/fpc/Ecomme ... eries=Q550
A lot more money thanks in part to the Windows OS, but again a fully functional computer.
The downsides as I see them are the price, USB 2 (not USB 3), no option for larger spinning hard drive, not listed as SDXC (only SD/SDHC), and extra $100 to get the 4 cell battery for the 8 hour performance, no ethernet without and adapter.
They could have used a fold out X jack for ethernet, but now you need to tie up the only USB port it has to get wired connection which is kind of required for some of the work that I do, along with a USB to RS232 adpater, so now I would need to have a hub with me at all times....
Still going to think about this since I was looking at spending more than $200 on an Android tablet, if I was looking at dropping the amount of money for an iPad2, there would be little thought about which I would buy now.
