I’m about halfway there on the upgrade of the larger notebook harddrive and 10.5.4 with XP BootCamp (all of this is to get SolidWorks 2008 Education version running, mind you). Leopard is noticeably faster than my old run down version of Tiger. Or at least that’s what they’d have you believe. No seriously, this system is running snappier with the fresh install. I’ll still need to migrate all my iPhoto stuff, as the version of Leopard I bought didn’t come with iLife. I’ll need my address book and some bookmarks but that’s about all I need to migrate. It’s pretty straightforward. I did create a bootable external drive backup of Tiger in case something goes wrong using, Carbon Copy Cloner. That worked pretty well too. You just hold down the (alt) option key at startup and choose the firewire disk you want to boot from.
Currently the TimeCapsule is backing up this fresh install. The TC 500GB drive is a little loud when writing even though its encased in white plastic. We were able to play a DVD video_TS file over 802.11n the other night to the TV. As a note, you should turn off Time Machine automatic backup when you’re planning on watching something on your laptop because it’ll keep trying to backup while trying to stream the video and it’ll get choppy. Lesson learned. Under XP it said we’d connected to the router at 128 MB/s. So yeah, this stuff seems to be working alright. Another nice feature of Leopard is in the Dictionary Application it goes to Wikipedia as the default. Pretty cool.
