HTC's new entry level phone, Explorer will have 384 Mb of RAM.
It is coming with Sense 3.5, which could be higher in version number yet weaker in features, but if not so, memory may not be an issue.
There are ports, well, ROMs with sense 3.0 and the phone copes with it quite well.
Not the smoothest, but what the heck.
Noone knows if HTC will give a damn about bringing Sense 3.0 to DZ.
