More than likely most Mac owners will have one of the following: an external drive, a network drive, a bootcamp partition, a USB memory stick, etc. That means OS X will react differently to drag 'n drop for all of those items.
Mac OS X reacts the same to all of those except partitions. The rest are all technically external drives. It's not like you have to learn anything new for each drive you use. Tell me, did you complain to Apple about the inconsistency? Maybe there's a bug present that they're not aware of?
I didn't write Mac OS X, you know. As I don't have a partitioned drive, I wasn't aware of it. When you talked about it, I agreed that it was illogical and inconsistent.
I'm not arguing against cut and paste, I'm simply saying, as I did before, that Apple has probably chosen to leave it out until they figure out what to do with it because it functions differently with files and folders than it does with text. You can't argue that. You really have to leave undo out of the argument. Undo is a separate system function. If you cut text and cut more text, the original text is GONE. If you cut a file and cut another file, the original is UNCUT. The two are different, it's a fact.
I agreed that Mac OS X is inconsistent when it comes to quitting the application. It's inconsistent in many places, like Windows and like almost everything with a GUI.
No, it's not a likely scenario. 90% of the computing world uses Windows and I don't see, hear or read about people having issues with cut 'n paste. The only time I've seen cut 'n paste become an issue is here on macrumors.
I disagree. It's a perfectly likely scenario.
The iPhone's cut, copy and paste is hardly mindblowing. The reason it took so long to come out is because they only have so many software writers and copy 'n paste was probably lower on the list of things to code.
It does appear to be well thought out. They didn't just slap it together because now they have time. Sure, I bet it took a bit for them to figure out the best way to store the clipboard and retrieve it, but I think it's clear that Apple's programmers highly value UI. They wouldn't just slap it together and hope it works à la Microsoft.
- iChat with its screen sharing feature built-in.
By the way, there's an app in Leopard that is specifically for screen sharing. You can use it like a remote desktop and you don't need iChat open.
As for your cons:
- Save Dialog - I wholeheartedly agree, that's the only change I've ever really, really wanted. When I first bought my PowerBook, I checked every release to see if they added it. I finally gave up somewhere in the middle of Tiger. I'd also add the ability to copy from the new folder dialog.
- FTP - Like someone else said Command+K. It's been there for ages.
- Tiling Windows - I don't think I'd use it. At most I'm using a few windows at a time. It'd be useful in Photoshop though. And wait, Photoshop does it!
- Caps Lock - What computer are you talking about? My old Apple keyboard reacts the same, and so does the keyboard on my PowerBook. Further, what exactly is the use of caps lock? I've never found that key to be very useful. If I need a word in caps, I hold shift and type. I have big hands and I'm a touch typist, so I don't need to use my pinky if I don't want to. Why would anyone need to type in caps for any extended amount of time? If you give me a reason I'll be happy to acknowledge it. The only time I ever use the key is to keep After Effects from displaying frames as it renders, unfortunately, this applies outside of AE to, so if I have to type, it shows the frames anyway.
- Full Screen Button - Um Apple, if you're listening, please don't do this. I don't need my UI to be cluttered with another button I won't use. Thanks. When I used Windows I used maximize, now I don't miss it at all.
- Blu Ray Support - This would be nice, but I don't own any. I don't pay full price for DVDs, I won't be paying double a DVD price for a BRD. Yeah, it looks awesome, and yeah I have a HD LCD panel on my computer and on my wall, but $25+ for a movie is nuts. At my old job, we tested how our Blu Ray player looked with a BRD vs upconverted DVD, and the difference wasn't as big as one would expect. In fact, it was hardly noticeable.
- Button Size - Is there any chance you're talking about an Apple Pro app? For some reason they do that and get away with it. This one is really the fault of the software developers, not OS X specifically.
- iSight Controls - What are you going to do with that camera? Shoot a movie with it? Would you like adjustable aperture too so that you can get really nice DOF while you're talking to a friend on iChat? I guess it would be fun to play around with, but how many people would use it to justify implementing it?
- Forward Delete - You know I can see the usefulness in this, but I never use it on my full size keyboards. I know a lot of people do. I just rarely need to forward delete, but when I do, I hold shift and arrow to the right until the text is selected and then just delete normally. I don't know why one would end up needing to forward delete often enough to complain about it.
Hold down the Option key.
You know, I forgot about that. Touché.
, no doubt. I use it every 20-30 seconds!
