I don't have the trapdoor cover for my A1200, so I guess it'd have better ventilation without it anyway. I remember why I thought I wouldn't get the subway! It needed an accelerator or something to work, and I didn't have one. If I did get one, I'd probably get the Subway too. The price of accelerators is too high for me right now. $200+ for the ACA1233/40!
I mean, a A4000T would be better, but the ones on eBay are $1,200 or more!
What issues did you have with the ACA when you mentioned it wasn't quite so friendly?
