I bought Win8 ONLY because it was $70.  It seemed like too good of a deal to pass up, as full versions of Windows 7 are north of $200.  I'm only going to install Win8 on my SECONDARY desktop PC.  I wouldn't dare take a chance on ruining my beautiful, highly-customized Win7 setup.  My primary machine will still run Win7 for a long time.  So even if Windows 8 sucks, it's still a win-win for me. 

I'll stick with 7.

mhh never thought of that good point... all i was trying to say is that i see the potential but i dont mean that it would replace a desktop pc on a daily basis but that the power of the surface pro would be up for the task ( in some cases). I dont know if the touch screen would be still active if you would use the keyboard touch cover on it and add a mouse ( would be interesting to know ) but as you said the screen would be still very small.
If i would be a student still i would truly think about getting one if the price would be a little lower - I could see me using it for presentations it has a VGA output as far as i have seen you can make notes on pdfs and use it like a laptop without having the wait of one.
I dunno  - i dont want you to give up your laptop or your desktop pc for a surface / no no iam a desktop pc user myself
like i said i dont know but im sure that it will sell along W8

Sure there are advantages. I have 2 Motorola Xoom tablets which i use as dlna/internet streaming endstations for my flatscreen tv's in the bedroom and kitchen.

Handy as hell. Hooked up via HDMI cable i can watch movies, listen to music, surf a bit etc in bed on my tv. Who needs a smart tv?

Outside they are pretty useless in sunlight, whichever the make. In europe wifi in the train is spotty and then i'm being kind. Free wifi is only in MacDo which i can't stand because of the horrible stink of old grease, using my mobile as wifi hotpot is risky since i live at the frontier of two countries, risking huge data cost.

So pretty much any serious use of a tablet outdoors is limited to large cities. granted a lot of people live in big cities, but also a lot don't. Furthermore in most big cities walking around with a tablet in your hands is equal to putting a sign on your head that says: Mug me.

In a nutshell a tablet is handy when you have a good (free) wifi connection, indoors, and when you have a table/desktop to put it on.

In effect it's only really useful where you would put a pc anyway.

Yeah, i've got splashtop too. Even handles multi-monitor setups very well. But doing it on the tablet directly is too fiddly for me with that tiny screen, my fingers are too clumsy, on the tv it is alright.

What is fun i've installed Multiplicity from stardock so i can also control my server with the tablet via my pc.

People tend to foget one doesn't stay in their 20's forever, one day also those who can easily see the tablet's tiny stuff will get bad eyes. It's pretty shocking to see how no-one realizes that in 20 years time they'll be cursing the day they startred using a tablet just as so many people are now practically deaf at 30 due to mp3 megaphones in their ears for years..

I'm not having any problems with the tablet in that regard, but then my tablet screen is 10.1" and that's quite managable for me, from both the viewing and the 'touch' aspects.  I doubt that I'd want to go any smaller, though.  Those 7" tablets are too fiddly for my liking, though the one I/we have is handy for taking down the street to go shopping... we use it for the shopping list and calculating what it all comes to, etc.

I'm near 60 and my eyesight and hearing aren't too bad, so I'm not having issues with any of that.  I can see what's on the tablet well enough and I can see everything on my PC screen well enough.  The only difficulty I have is with printed material sometimes.  I do need glasses with some of the finer print, but other than that my vision is still quite good.

I used to listen to my music up loud, right through my teens, 20's, 30's and well into my 40's, though that was usually through my hi'fi system speakers rather than headphones, but I sort of grew out of that around 45ish and became... uh, more like my parents: "Turn that bloody racket down!"

I get your meaning, though... which is why I don't spend a lot of time using my tablet.  I prefer using my PC anyway. It's more comfortable and I just feel more at home on it.
