I have been running Windows 8 on the same model (MacBook Pro 13" (mid 2010) for about a month and haven't experienced any issues with it so far. I am not 100% certain that the trackpad gestures all work, however, most of them seem to, I was able to adjust the clicks to my preference and scrolling up and down and sideways works.
I had been waiting for Apple to issue properly supported drivers just because I like to ensure I keep everything as up to date and compatable as possible and I am rather annoyed that Apple isn't supporting this model but at least you can get it working. I also own a 17" MacBook Pro 2011 and a myriad of other Apple products and to me it is important that my laptop is able to run Windows even though I use the OS side more frequently. If Apple is not supporting Windows 8 in the hope that people will just buy new MacBooks more frequently I think it will backfire on them because that shows they don't care about thier customers. That is a mistake in my opinion because I would have bought another MacBook perhaps in a year or two but I won't if I think Apple is trying to force customers to upgrade early unnecessairly.
In my case I installed Windows 7 first and then upgraded to Windows 8. I made sure to fully update Windows 7 before upgrading. Initially the trackpad didn't work so I used a USB mouse and then updated Windows 8 with the most recent patches, etc. Then to get the trackpad working I followed advice I found on another forum which basically consisted of going to the drivers section (Device Manager) of Windows 8 and changing the drivers which were marked yellow (as not working or compatible) to USB drivers. My trackpad then worked and I went on to make some changes to get the clicking to work the way I wanted and to lower the sensitivity of the scrolling. Now I am perfectly happy. Unfortunately, I don't know how to install Windows 8 directly (clean install) without installing Windows 7 first but if you search some more I think others have done it. All I can say for certain is that you can install Windows 8 and have it work really well on this MacBook if you upgrade from Windows 7, it just takes a bit of searching on forums as to how to get the trackpad working smoothly.
The only other thing I would note is that if you are short of space on the Windows partition, you can free up a lot of additional space by deleting the Windows 7 recovery once Windows 8 is up and running. I was initially surprised at how much space Windows 8 took up but after searching other forums I found I was able to free up a substantion amount of space (I think around 30GB if I remember correctly).
I wish I could have been of more help but I wanted you to know that it was at least possible to run Windows 8 well on your MacBook Pro model. I am really happy with its performance now on mine.
