Yeah... I currently have a 512mb ext partition on my sdcard in my Dream, and I have 200+ apps, and I'm not even close to thinking about getting close to running out of room. Until we start seeing apps that are 10mb+ on the Market (and I mean lots of those apps), we are NEVER going to worry about running out of room for apps on the N1. 512mb for apps is more than overkill. And, I'm sure we may see more huge apps on the Market in the future, but with Google releasing "official apps2sd", the answer to your question is yes. Forget about app size. Install anything and everything you want. You'll never run out of room.
