The computer's not "junk". I don't know what you mean by "nice" but it's functional. A computer is simply a tool! A costly, complex, versatile one yes, but still simply a tool.
It's the software that's rubbish! Well, it is Microsoft's for a start - then I have two e-mail accounts and neither use Outlook directly and simply, as MS used to offer when it still held promise of trying to improve its programmes.
My ISP, BTInternet, seems to use its own e-mail / internet-access programme, but the other account has Outlook and browser bundled with blasted MSN. Both systems are similar, bombarding you with gimmicks, adverts, photo-galleries with pseudo-emotional titles, and so-called "news"; wanted or not. That's "junk" to me - "junk mail". Even if a news headline looks interesting you've little time to consider selecting it because the editors' personal selections change every second or so.
You've no choice. Outlook no longer exists alone, as far as I can determine.
BTInternet is marginally better than it was. It used to be tied up with the execrable Yahoo!, an idiots'-fest even more "junk" than MSN.
