Alsoft's website is a piece of junk! It took me five minutes just to figure out how to order the damn upgrade. When I finally got there, I realized that they are showing two different prices ($39.95 on one page, $79.95 on the actual order page).
I prefer the download model where you can get the download at any time and just have to enter the serial number to activate it.
Additionally, the only non-snail-mail option is for them to e-mail it to you. WTF! Just hook me up with a browser download. My email limit is too low, so I have to wait for a CD, which inexplicably will take 2-3 weeks.
Diskwarrior is great and worth the trouble (or at least past versions were, who knows about this one), but c'mon!
