It's over a year since I have my G1. I'm still loving it mostly, but there are signs that I need a new phone whenever a new one coming.

One of the biggest annoyance I have is the probably the CPU, or so I believed. The power of Android is I can run multiple programs at the same time and quickly switch among them. But in reality, G1 is getting sluggish when I have Twitdroid running and listen to podcast/music. Even with no program in the foreground, the Home screen with widgets (I have 9 running across 3 screens) already showing slow response from time to time. The same when I run Google Maps, surf the web, and in general multi-tasking. I do not think this is out of memory issue, since system monitor reports memory usage is under 80%. So, I think a faster CPU is needed, a Snapdragon is a requirement for me and let's hope it's not a battery eater.

Battery life is the next major short-coming on G1. Granted, I run a lot of things that keep the phone active, but it looks like making a phone call or two eat up quite a look of battery. In a typical day, I'm able to keep my G1 away from charger if I only listen to music and read tweets lightly while on MUNI. But soon I talk on the phone, I have to charge the phone otherwise I won't last til leaving work.

In addition, I have yet to have T-mobiles HSPA 7.2(Mbps) coverage, which my G1 can get at. But with T-mobile deploying HSPA+ (@21Mbps) next year, there is no reason not to have more downlink/uplink bandwidth.
