To use Windows is my habit. I've been using it for 12 years, since I've got my first PC! Now I'm on Mac but I still use Windows through Parallels Desktop to run some Windows apps and PC-games.
I have a reliance on Windows XP at the moment for working with Visual Studio. I largely run Windows through Fusion though so I can use the spaces on Leopard. I also do some graphics work, which is where OSX comes in to play as it just works better.
Looking to ditch my PC desktop for an iMac soon... can't wait.
Microsoft Money
EA Tiger Wood PGA Golf 2006
MAME32
I run them of my MacBook Pro using Bootcamp (XP Pro)
I have almost ten years of data in Money and don't want even think of trying to transfer it to another program. Also the Mac version of Quicken is in a word crap.
There is a Mac version of EA Golf, but the Windows version is the previous year and came with other EA sports games for only $29.
Also I know there is a MAME for Mac, but it isn't as updated as often as the PC version and the Mac version always seems to not work as smoothly for me.
Windows Quicken -- GNUCash would suffice for me, but I've never figured out how to install it into OSX. It seem even more complicated that installing in Linux.
SAP GUI - For when I do some work from home. I know about the Java version, but I also need to connect to a BI 7.0 box through BEX.
I did know. Downloading and then watching tends to give better quality. It's a case of trading the quality against the wait while it downloads. The quicker the BBC gets its act together and opens iPlayer to other platforms the better.
The *only* thing I use Boot Camp for is PowerDVD. I don't have much hope but I'm crossing my fingers for HD DVD support in 10.5.2 so that I can say goodbye to Windows.
I use Windows XP via Fusion only for site testing in IE7 and Firefox-Safari/Windows. I rejoice in my complete abstinence of using a dedicated Windows machine.
I was thinking of sticking NFS Carbon or Most Wanted on there, but in reality I'd never play it and it would be a waste of space.
