I've had the Surface Pro (Version One) for about 7 months and I have been very happy with it.. It's replaced my laptop
and my iPad - a nice all-in-one device. I especially like the digitizer, the pen "writes" smoothly enough that I can doodle in Photoshop and use the OneNote like a pad of paper. A huge difference from the iPad "fat finger" writing. I also like that I can run my regular software on it, no cheesy "apps." The USB port allows me to plug it right into my TV and watch Hulu (using an HDMI Adapter). I can also use Overdrive to get books right from the library and use it as an e-reader. I've got Office 365 and can easily pop open a powerpoint or Word doc on the go, and I've even connected it to projectors for business meetings without any problems.
I kept my old laptop as a backup, but haven't needed to pull it out.
It's not a perfect device:
1. The screen is too small to work on it comfortably for long periods. (I use my desktop during the workday.)
2. It's not loud enough. If I play a video while I'm cooking dinner, the stovetop fan drowns out the audio.
3. No hdmi port and only one USB port.
4. A tad too heavy.
5. Limited space - I have Office, Photoshop, and Indesign installed - but I've run out of space to install big Adobe apps. I think I can expand the storage a bit via an SD card, but haven't tried.
It sounds like a lot of my quibbles will be fixed in the next version, so I may need to upgrade.
Hope this helps.
