Well when was it cheap?
Arguable. Even more so now that PT 12.4 has been released.
Logic's instruments do not sound very good though, but yes they're a good starting point. And Live isn't exactly cheap either by the way.
Well in terms of someone getting into music now, the presets in Logic Pro and Ableton are much better for someone working in the box than Pro Tools.
For the purposes anyone here is going to be using a DAW for, if they're the type of user who Pro Tools would appeal to REAPER is almost certainly a better option. No messing about with AAX plugin support (most of my plugins do have AAX versions but certainly not all), a much, much lower licensing fee, no silly hardware dongles etc etc.
Consider plugins for a moment - if I buy a plugin, I can pretty much guarantee it'll be available in VST and maybe even AU format. It might come in AAX format, or it might not. Meanwhile there's plenty of free VSTs as well.
The main reason I can see for using Pro Tools now is if you're interested in a Pro Tools|HD setup but odds are if they're asking about it here they're probably not. Otherwise Pro Tools very much feels like an example of something that's the industry standard for little more reason than because it's the industry standard, and recent years are giving the impression that AVID don't really seem to have a grasp on what they're doing.
If you need to exchange work between studios then Pro Tools is the obvious choice because it's what they're all using, and I completely understand why studios would opt for a complete AVID setup, but the reality is you're not them, and you'd probably get by just fine on something a whole lot cheaper.
I have used Pro Tools, admittedly after using just about every other option, and whilst I wouldn't say I thought it was by any means bad (it's a very capable DAW), my impression was very much one of "why would you use this when there's so many other great options out there". If you're using it already and you're happy with it, that's great - keep using it, but for people going into music now it's really difficult to recommend.
Regarding Logic's instruments, I'm aware that they don't compete with the top VIs, but compared to a lot of virtual instruments out there they really aren't bad at all. Alchemy is downright impressive and a lot of the stock plugins are fantastic. Personally I'm not too fussed about them - I have my own plugins that I use and I'm very happy with, but for someone going into music now, who doesn't necessarily know what they want yet in terms of third party plugins, Logic is an awesome starting point.
