Well, I do have two 8GB SDHC cards on the N800; so until a SDK is released, that will give us the posibility to patch the new kernel version with SDHC support (or build in SDHC support from Nokia will be nice too) and also add SDHC boot (that improves overall system performance), I'm sticking with my current version.

Sure Mediaplayer is not great, but you do have Mplayer that plays way more formats and it's overall performance is very good (specially on the very last version from the 22nd March). Youtube might not be usable, but I've got used to download a converted version using Videodownloader or similar.

Little things like the camera app are also available for the old version.

And anyway there is no improvement that matches having 16GB of Video, MP3, Photos, Maps and other data on the N800. So I'm definitely waiting a bit more.
