Okay, I read it. Yes they seem worth the risk. Because...
Every house needs about 1 tablet per person, plus .5 desktops per person. We have 6 people. $300 per person is not in the budget. I did just buy 4 $100 a9 cortex tablets, 1 ghz single core. I do need about two more. Maybe would splurge up to $200 on a nexus 7 quad core, simply because there is room for snappier behavior, since even a stripped down linux, the os is still a pig compared with windows 95. Kingoffice is the best spreadsheet, but still slow and limited compared with a 1985 dos 123 lotus.exe.
Though I may wait until someone builds an android with a screen that can be seen outdoors. Some ar coating, with oled technology. I am still stuck with a 1993 palm top for estimating spreadsheet, since everything works quicker, more powerful, and I can see the screen outdoors. And the 45 hour battery life (with aa backups), means it always works when I grab it. Not true of any 5-6 hour runtime device.
