That's it. Time Machine doesn't work with parallels on my common setup (MBP with lacie ext hdd), Mail just refused to open, photoshop has crashed, three times in two days a transparent curtain has descended and told me to reboot, screen artifacts remain after closing safari, etc. It's not worth it, yet. At least for me. I use an intel mbp 17' all day using PS and FCP, wireless (yeah, that's messed up too) and some soundtrack pro. It's just after 4am here in the mountains and I am going to spend the next four hours going back to tiger.
