LOL Thanks for the idea but i would not know where to start with WinUAE ,but i do have a question ,why would anyone want to run Amiga Games and all the rest on a pc ,when theres loads of Amiga 1200,s 500,s 600,s all over the uk ,spain, America every week for sale ,week in and week out ,Ebays full of them ,and each of us must have at least three each and a pile more in a hide away up the Attic ,i bet theres not one of us here who own an Amiga can put there hand up and say that they have only the one ,so i am confused as to why the use of a pc to play Amiga ,taking in to account that this is what WinUAE is used for and the Amiga certainly does most things brilliantly ,i do have to say that maybe the cost may come in to it ,as the running costs of an Amiga far exceedes any thing i ever spent on my x wife which probally explanes why i now live alone lol with my beloved Amiga,lol lol ,good idea though my friend,best wishes Brian.

Most people have PC's at their places of work. With WinUAE, they could sneak in an Amiga game at break or lunch on their machines.
Also, for pure performance, an emulated Amiga on a modern machine, runs circles around the fastest fully loaded A4000's. This could be useful using 3-D rendering applications. Using SysInfo, my Quad-core PC reports being 90 times faster than an A4000-040. The speed of my dedicated 2.5" IDE drive is reported at 17,096,347 Bytes/Sec. This is faster than any of my SCSI drives on my real Amigas. I can also set it up with 8 MB of ChipRAM. Only 2 MB is possible on my real Amigas. I don't have retargetable graphics card on any of my Amigas, but on WinUAE, I can use P96 to do 2-D and 3-D acceleration and get resolutions up to the max of my PC. I have done 1920x1080 full screen with WinUAE. It is rock stable and fast, although practically, I would go no higher than 1280x1024. It's a great resolution for desktop publishing like PageStream and Professional Page (especially for viewing dual facing pages). And with Deluxe Music, I can have multiple scores opened side-by-side for editing and copying and pasting. Most games don't take advantage of RTG because they mostly use Amiga's native modes, but most productivity packages can.
And of course, as you mentioned there is price. Most decently equipped A4000's on Ebay will go for over $1000 is the US. You can get decently equiped PC desktops or laptops for about $500. Add the $49.95 for the premium edition of Cloanto's AmigaForever, and you have a super Amiga for about half the price.
My only problem is playing native samples on Deluxe Music. Often times, the timing is off on some of the more complicated scores. That may be fixed of time with faster technology and finer tuning on WinUAE. In the meanwhile, I can compose my music on WinUAE using MIDI output. Then transfer them to a real Amiga to play using the Amiga chipset.
I still have a ton of Amigas (see my sig). So for software banging the original chipset (OCS, ECS, AGA), real Amigas are better for now. But for those that use RTG, AHI and more modern things like IDE, USB, large screen monitors, networking, WinUAE is better.
