Yes I think so, as time permits. One of the applications I’m totally into right now is VMWARE. One my laptop I have seven databases now. 3 in windows vm (8i, 9ir2, 10gr1), 3 in a small linux vm (9ir1, 9ir2, 10gr1) and one in a big linux vm pretending to be a 2 instance RAC cluster using ASM and OCFS (you can get the last one from here yourself, just have bandwidth. Click on the database link on that page. Comes with 90 Trial of vmware).
Using vmware, I don’t install software on my base laptop, I install it in a vm – I cannot “damage” anything, it is a very safe environment. I can do OS/database patching, upgrades, whatever without fear of accidentally knocking myself out. Vmware has this neat “snapshot” and “revert” feature. As someone that likes to play and test – this environment rocks. As someone who needs to setup a strawman – try something out, beat it to death and start over, this has been a big change for the way I work. Doing training and other things are really easy now. Instead of a single machine trying to run 20 instances, each desktop runs it’s own virtual machine and everyone, everyone has the same exact setup. No install this database/app server/whatever on 20 machines, do it once and copy the vm’s.
I even use vmware on some of my larger machines – as playground. Something to look into. If you wanted to play with 10g RAC, ASM, OCFS, Grid control, the whole thing and have the bandwidth, you might check it out. If you do training, it is definitely a piece of software to have. If you have a single machine and need “test areas” (test that upgrade, test that patch, test that new code) in a single test machine, absolutely something to look into.
