rtcvb32: I see the inherit limitations, and while turned off about it doesn't mean i hate them. But you can't really upgrade them, if they break you can't fix/repair/replace the individual broken parts.
You can upgrade parts of them. I mentioned elsewhere that just a few months ago I expanded my main gaming laptop's RAM from 8GB to 16GB, and HDD size from 1.5TB to 6TB (by replacing two 750GB HDDs and an internal DVD-RW drive with three 2TB HDDs; I use a DVD-RW drive so rarely that an external USB DVD-RW is more than enough for me). And before you ask "why do you need that much HDD space?!?"... I have both Windows and Linux running on the system side by side, I like keeping e.g. the whole MAME/Amiga/etc. collection on the hard drive so I can play the games whenever I want, and I generally like the feel I don't constantly have to think about cleaning up the HDDs in order to be able to install and download something else.
True, you can't normally upgrade e.g. the CPU or the GPU on a laptop... but when I think about my past gaming desktops I had, I hardly ever did that anyway (I never upgraded the CPU on a desktop, and only once I have upgraded the graphics card).
Usually when I felt it was time to upgrade CPU and/or GPU, the system was so long in the tooth already that it was better to replace it completely. Quite often the motherboard form factors had already changed (ie. new motherboards wouldn't necessarily fit my old PC case), the graphics card busses had changed, the preferred video ports had changed, the new graphics cards required more powerful power supplies and the connectors between the power supply and the motherboard had changed, etc. etc. etc. etc. etc. etc. ad nauseam, urea acta est.
No, it was usually just much simpler to replace the whole system, many times including the monitor. Maybe I could keep the old USB keyboard and mouse, though.
Usually when I upgraded single components in my desktop PCs, the upgrades were the same that are trivial to do on laptops too: expanding the RAM, or replacing hard drives. Those are very easy to do on laptops.
EDIT: As for changing broken parts... what usually breaks in a laptop? The only broken part I have ever needed to replace in a laptop is either the battery or the fan(s), and those can be replaced even by yourself. I changed both fans for my aging gaming laptop half a year ago or so, as one (of the two) fans started giving loud noises every now and then.
The operation was somewhat laborious because I had to detach and lift the keyboard in order to get to the fans to replace them... but there were good and detailed instructions on the net how to do that so I just followed them. Then again, I do feel ASUS could have made the operation considerably easier too, like why not make it possible to change the fans from below the laptop? Then one wouldn't have to detach the keyboard. The fans were visible anyway from below when opening the lower lid, they could have been easily replaced from there as well. Anyways...
Depending on the model, battery may be easily replaced as well. If it is internal battery, then it is harder but doable. Then again, a laptop is usable even with a dead battery, it works normally when connected to power outlet. In fact I have detached the battery from my gaming laptop normally, and insert the batter only if I know I might be using it without being connected to power.
rtcvb32: Yes you can. However that's extra equipment you have to lug around because the built-in ones are more or less inadequate for... long term comfort (
and they drain the battery faster). The keys are tighter and smaller together, the mouse touch pad might get brushed while typing and change the focus of the program or do odd things. The tiny speakers offer sound but not very high quality or loud enough.
The situations where those limitations matter are situations where you couldn't use a desktop PC at all.
So, yeah, true, if I take a laptop out of my bag on a train or airport or airplane, I probably have to do with a "lesser" mouse/keyboard/monitor than if I was at my home or the office... but then that comparison is meaningless because I can't use my desktop at all in the said situations and places.
When I am at the desk at my home or office, I have access to exactly the same monitors, keyboards, mouse and speakers I'd have with a desktop. Sometimes even better, ie. if I now had a desktop in the bedroom, I couldn't use my TV's superior stereo audio system with it like I now can with my laptop, which is connected to the TV with HDMI.
My laptop's integrated keyboard is ok for occasional use and non-action games, but if I want to write more or play more seriously, my trusty wireless Logitech K360 keyboard is great for that. It is small and flat enough to fit into my laptop bag, yet it doesn't feel cramped (it has a separate numpad too), and its feeling is great for a chiclet-style keyboard. Heck, it's feeling is even better than the bigger wired desktop keyboard that my employer gave me in the office (it is bigger in size, and also a flat chiclet-keyboard; chiclet-keyboards seem to be the trend nowadays even for desktop systems).
For me the only advantage with a desktop gaming PC was that if I wanted to have a very powerful gaming system for the newest games running in highest 4K resolutions, Hairworks and shit, and didn't care about e.g. portability at all, then it would be considerably cheaper with a desktop system. Anyway, being a active GOG customer suggests that I am not really playing the newest games, I tend to wait a bit until the bugs are ironed out and all DLCs released. This will go also for Cyberpunk, even though I have preordered it.
THIS LONG MESSAGE WAS WRITTEN WITH A WIRELESS LOGITECH K360 KEYBOARD ON MY LAPTOP WHICH IS CONNECTED TO THE TV, AND MY HANDS ARE NOT EVEN ACHING. HECK, I COULD HAVE WRITTEN EVEN 2-3 TIMES LONGER MESSAGE, DARE ME.
Oh yeah, and my laptop is currently connected to the power outlet, so the fact that using external mouse and keyboard uses a bit of extra power is irrelevant. The only times I use a laptop without being connected to power outlet is when electricity is not easily available, or the task is so small and short that it doesn't matter.
Heck, I can get power to my laptop even inside my car, if I wanted to.
