It is somewhat heavier than an ipad or android tablet, battery life is very good for a laptop but poor for a tablet.  Touch sensitivity seems a little less sensitive than iPad/Galaxy.  However, it runs full blown Windows, and it runs it FAST.  It blew away my 2 year old i7 based HP monster loaded with 8Gb of RAM.  What a Surface Pro really is geared for is a micro-laptop.  The size and keyboard/touchscreen combo makes it usable almost anywhere.  Set the stand up and it is very usable on your lap (even in a middle seat).  Battery life is around 5 hours with wi-fi.  This will be a great device for those who want a really portable laptop and need the extra input capabilities that a full keyboard gives.  If you need to use it as a tablet it can do that too, but if you really just want an entertainment tablet  then probably look at an RT, iPad, Galaxy, or Nexus.

Regarding the temperature section, I will add that although is true that on the backside the temperature is not really annoying, the heat is also transferred to the screen, being very unpleasant for touch handling. I have seen ipads never behave like this, they get hot on the back but heat is not transferred to the touchscreen.

I have two of these and have to say I cannot recommend until they fix the Wifi problems. Makes it nearly unusable even if using a RJ45 dongle. Just search Surface Pro wifi problem before you buy.

We have been waiting for a full fledged version of Windows to run on a tablet for a long time, but with such a large OS, I'm concerned about how much resources it uses up.  Still, it is a dream come true for me.  I want something more versatile than my iPad, but just as powerful, so I can use it for both my work I do at DISH and entertainment.  Now I use my iPad to watch my TV shows by using DISH Anywhere and my DISH Hopper DVR at home.  I love it because I can watch TV while I'm on the train, through the internet and get caught up on TV watching when I usually don't have time at home.

I bought one, and its too heavy to use as a tablet.
The display angle is too low with the stand.
And Microsoft should have put a hdmi port on it.
Non upgradable hard drive or memory is a big mistake.
A holder or internal sleave/slot should have been made for the pen, the magnetic holder is not strong enough, and where do you put the pen whilst charging.
The external keyboard/mouse sometimes disconnects for no reason, so you have to reboot to activate it again.
The rotation landscape/portrait is slow, and sometimes doesn't happen, because the o/s thinks the external keyboard/mouse is still attached.
The volume/sound is too low.

Apart from all that, it's an ok laptop, but a poor tablet.
Microsoft, the design flaws are inexcusable. What were you thinking?
Email me [email protected] if you want to know how to design a real hybrid laptop without making these basic errors.
Hang your heads in shame rather than patting yourselves on the back. Your job ain't finished.

Something's missing. I have 24" Full HD touchscreen running Win8 and a lot of times the touch icons are smallish for a regular size hand -- like the X-mark to exit the program. With this 10 incher, I see a lack of comment in this area a sore spot. Win8, although designed for a touch screen is nowhere near as finger-friendly as a 7" Android (I have Kindle HD Fire).
No IPS display and 1:30 hour limit for movie watching does not cut it for me.
