I certainly don't begrudge the lower resolution of the S1080. I have a Fujitsu P1610, which has an 8.9", 1280x768 resolution screen, and I find it almost impossible to use with my normal reading glasses, because the text etc is so small. To that end, I can see exactly the same issues with a 10" tablet running very high resolution screens. And if you try to do any scaling, it can distort things, which makes it less than optimal.
I think one of the reasons that the S1080 and it's conterparts haven't done well in the marketplace, and especially with reviewers, is because most are enarmoured by the simple things that Android and Apple provides, cheezy apps etc. Most of those tablets are sold as playthings and reviewers etc are always loking for the next best plaything with new bells and whistles, not always practical tools.
The other reason is that Windows 7 isn't considered as a serious OS contender in the tablet market, and especially because the 'app' store is so bereft of fun things to download. That's one aspect of the marketplace that Windows 8 in the RT version is trying to capture, but retain the business end with the Pro version; though I still have my reservations about the 'not now called Metro' interface, I prefer the desktop.
One reason why I investigated the S1080 to a greater degree than I would normally have done, was due to the bagging it received, despite clearly having more functional features than any other tablet. After handling one in the flesh, it was a no-brainer for me. All I really think that the S1080 future should hold is a more (energy efficient processor, more RAM capacity - seems like the S1081 has that) and a more flexible BIOS. Mind you, I still think the S1080 is a better overall device than many of the newer tablets.
