Gerard - I noticed that you made this same comment on the Reg's review of the Liquid but didn't reply when the reviewer asked you for examples of missing apps. I took delivery of my Liquid from Expansys last week and found all 18 of the apps on my G1 - 4 payed for, the rest gratis - in the Android 1.6 Market and all work.
With a few small exceptions - HTC have released some Sense widgets that only work on handsets running the HTC Sense UI - the Android Market is the same no matter what handset you are using.
Either let the rest of us know what apps you had running on your G1 that you can't find in the 1.6 Market via the Liquid or the ones that you can find but can't get working on the Liquid or quit complaining! BTW, if you have an app that works on the G1 but not the Liquid that is a fault with the app developer, not with the handset maker!
