Stubear: KDE took about 8 hours on my machine. I haven't done OpenOffice yet.
I purchased Crossover Office a while ago and so I get free upgrades. Microsoft Office XP works out of the box with that so I'll use that. I highly recommend Crossover Office for those that miss Photoshop and are in linux. I do understand that GIMP is around, but Adobe Photoshop blows GIMP away and it works flawlessy in Crossover. Same with Microsoft Office XP; both work excellent.
I use it for other things as well, but the sole reason for purchase was Adobe Photoshop.
It was money well spent.
