I had to call tech support (nice folks, btw) to discover that low space correlated.  But seriously – why couldn’t there have been a warning on the phone?  A simple pop-up would’ve been fine!  It’s not like this is my SD space – it’s INTERNAL space.  I really expect them to keep up on that or prevent me from, uh, limiting my phone’s functionality.  Seriously.  Also, the internet cache doesn’t clear automatically… at all?  I mean, what?!  This is a phone, not a laptop, not a PC.  I expect a bit more vigilance in keeping space down and making sure that the phone is, first of all, a workable phone.

I guess that’s been my biggest complaint about the G1: it should, by default, ensure that it is always a functional phone.  I still get times where the Contact list crashes, or I can’t get to the dialer as the phone behaves sluggishly (without 6 apps running, at that, or anything non-Google running).  I understand that your memory is also a pagefile, but come on!  Set aside space for it, don’t make it my responsibility to fish around and find out that you’re suffering.  For ONCE, learn from Windows by reserving that pagefile AHEAD of time.  It’s just for this reason!
