Joohan - I've been thinking along the same lines - my 770 does to be honest feel a /little/ on the sluggish side (opening a bowser or the news reader is a 'crunch-crunch-crunch...drawing window...rendering text...and...open' rather than a 'spinning cursor...PING!' experience )

Now if you look at what's been going on in the HTC community (I don't have one but I know someone who does and have been reading up on it - would have bought one if the announcement of the 770 hadn't stopped me!), there are various 'hacked' versions of the OS that for example will load a whole bunch of useful apps from a compressed rom image after every hard reset, various tweaks, memory management etc etc. Basically lots of clever stuff done by the 'slighly obsessed' side of the user community

To this end I'm hoping that several things will happen:

(sure I'll get flamed for this one but here goes... )
1) that NOKIA having made their R&D investment will leave the hardware alone to make some money for them, and not release more similar devices too soon - much like what happened with the original Playstation whose hardware didn't change for seemingly ages and ages, developers learned a lot of neat tricks and the software increasingly took advantage of various quirks and all sorts clever optimisations were implemented - PS1 games were immensely better towards the end of its career than the first batch released..
2) Hopefully it'll also be a little while before a competitor (Sharp? Microsoft?) release something similar, to allow the 770 to reach a certain 'critical mass' i.e. being 'pretty much THE (only) internet tablet' will drive many developers and hackers to the platform. (Very interested to hear what others think about this - maybe I'm completely wrong and maybe the existence of a number of competing platforms don't dilute innovation/developer uptake?)
3) Because of the hardware staying the same, and the lack of competition, development/hacking of the OS will go through the roof in a way that perhaps has not happened on desktop Linux due to the dispersal of developer talent among the various distributions (this has always seemed like a bit of a waste to me since so many distros overlap so much in purpose and functionlity....again, perhaps I'm missing the point?)

Basically I'm waiting with bated breath for various optimised/hacked/cunningly recompiled OS images springing up for download, complete with all the 'laptop-like' features that like you, I really rather want (divx, mobile web server, voip, java etc, as well as overall improved speed/responsiveness)

In a similar vein, and perhaps warranting a separate thread - why not mix in the subject of hardware hacks?! Has anyone mentioned overclocking yet for example? USB charging? Antenna mods anyone? It's all a bit early for most of this - but I'm just kind of salivating at the thought of all the possibilities!
