<< Does OS X have a strong learning curve? How many task can it handle during work?(such as dvd burning and graphics work). Either way i'm still going to get one at the end of the year but i just want to do it right and get responses from the real users.
Basically whats your opinion on it? >>
OS X is unfinished/unpolished, so it's hard to say what it will be like at the end of the year. The "learning curve" is up to you. The basic interface is very Mac-like. It makes some slight departures from the old Mac UI rules, but nothing that will bother almost anyone but UI designers like myself. (I don't consider OS X a Mac since it doesn't follow the Mac UI rules, but that's my pig-headed opinion.)
There is a command line terminal to access the BSD architecture, so if you want a steep learning curve you can find it, but it shouldn't be necessary 95% of the time. Currently there are some glitches in the system like file permissions getting screwed up, and the accepted solution is to use the Terminal. There are a few other cases as well, but I suspect that they will get ironed out over the next year.
Speed is a handicap in the current incarnation, but Apple claims to be working on it. They just demoed the next release, and I have to admit it looks faster but I don't know what hardware it was on. Multitasking works quite nicely most of the time, enough so to say it isn't an issue.
It's impossible to say at this point how DVD burning and graphics work and such work since the current release doesn't have a working data CD-R burner much less DVD. The next release will. Graphic is also unknown for the most part since there are very few mainstream graphics apps available. Macromedia Freehand is the only big name product. Adobe hasn't released any yet.
Right now it's touch-and-go. I personally won't run it full time until all my apps exist natively, and I suspect that will be at least another year.
