Yeah, I think your biggest problem would be trying to use an emulator.
My main computer is a home-built with an Intel quad core @ 3.2 GHz (QX9770 Yorkfield), 4GB RAM and a GTX285 video card with Windows XP. At the time I built it I spared no expense and got the best of everything, of course that was several years ago so now it's a glorified paperweight.
Still not too bad though and I had heard about the emulators being slow and although it's definitely much more laggy than my EVO4G, I didn't think it was too bad.......
..... until I brought my project to work with me on my notebook computer, a Toshiba Satellite A135: 1.73 GHz dual core, 2 GB RAM, shared graphics and Vista. What a difference! Compiling takes 3 or 4 times as long, which is okay, but using the emulator is the pits. It rarely wants to connect and when it does it is awkward at best trying to move views around.
One tip I can offer, if you find that it doesn't want to connect using the designer, is that for some reason I found that if I compile the project and wait for the emulator to load the app up, it seemed that after that I could exit the app then try connecting to the designer and it usually worked after that. Failing that, you may be better off using your real device although that's no fun to work with either when designing layouts.
Hopefully this makes sense. I've been up since yesterday afternoon (worked a 12 hour night shift last night). Slow couple of nights at work though so I made some good progress on the graphics for my app. :sign0060:
