Actually I have not had any major problems, and I did go ahead and upgrade my desktop a few weeks after my laptop. There are a few minor quirks, to be sure, and a few annoyances (like the way the firewall is handled in Leopard), but overall I can honestly say that I am happy with it, and really love a few of the new features (such as Time Machine and Quick Look).

I haven’t yet upgraded to the very latest version (10.5.4) but only because I am spending the summer on the road (with only my laptop) and don’t want to chance a problem that will render me unable to work. I hadn’t heard about any specific problems with wireless connections and 10.5.4, but I do know that with every version there is always someone (actually a group of someones) who do have problems. To be fair, as many if not more have troubles with Windows upgrades as well, so I think it’s just universal karma - some have trouble, most don’t and it’s a roll of the dice.

I appreciate that you’ve pointed out my lack of follow up review - I had intended to and just got busy, but I’ll write one soon.

If you have a blog of your own it would be great for others if you’d write about your experience with the last update shutting down your wireless network and exactly how you fixed it - there may be someone else still struggling. If you don’t have a blog please email me the details and I’ll write it up (crediting you) and post it.

Leopard is good–not great. Too many problems that take lots of time to fix. At best some problems seem just to be lack of documentation and lack of written support. At worst their are many bugs to be corrected. Which leads to a BIG problem: updates introduce problems into the system.

For example, the last Leopard update shut down my wireless network. Yes, after two days for researching the problem I got it working, but will this happen often? Will I need a full IT department to keep things working? Tiger was stable and I never felt that the next update would cause a work shutdown.

I like your review of the good, but come clean–what problems have you had that others can beware of? (my apologies if you have further reviews-this is all I saw.)

Be sure to backup everything first, and if you do decide to sell it and get an MBP, use the super-secure erase via Disk Utility to get rid of your old data.

Good luck! I’d love to hear how it works for you if you can remember to come back and let me know.

I am facing a dilemma. I currently own a 15″ PowerBook G4, the last model before Apple released MBP. I am pondering whether to buy a brand new MBP, or simply save money and just install Leopard on my PB. My primary concern is the performance of Leopard on my PB.

So, I wanna ask you how is Leopard’s performance on your 17″ PB, any slowdowns? Thanks!
