So what does the A1 have over the 1200?
Faster processor, better graphics, better sound, better networking, faster disks, improved operating system, faster boot times, you can put more RAM in it, newer hardware... etc. etc.
what can it do that the amiga can't do?
It can do pretty much everything a classic Amiga can do, only better. Take, for example, watching videos. You can watch higher resolution video on an A1 than on any A1200 because its faster.
what can't it do that the Amiga 1200 can?
* Output PAL/NTSC (although that can be fixed with a future Radeon driver update, I guess).
* Play games and demos that use the old Amiga chipset directly without using an emulator
* Read Amiga disks (at least until CW drivers are finished)
Cause the thought I have in my head just now is the A1 is a lower spec of a PC that uses the AmigaOS, I already have a high spec PC so I'm not needing another one which has lower specs to use amiga software,
Well, its not about need. I have a Windows XP laptop, which I could do everything I want. But I have an AmigaOne, and an expanded A4000 which get used as much, if not more than my laptop.
I use my A1 for web browsing, email, MSN messenger, IRC, gaming, programming, emulating consoles and old computers, listening to music, watching films, etc. and I do it because I actually enjoy using AmigaOS. I don't mind using windows, but I don't enjoy it. I really like the way AmigaOS works. I like programming for AmigaOS.
It feels faster and more responsive. I love the shell, I love the nice features such as ARexx.
If there was a laptop than ran OS4, I simply would not have a Windows PC.
