I\'m probably going to answer my own question but I currently have an SL-5500. I\'m running the current Sharp ROM. I have a wireless network at home and do have wireless CF card, but I seldom if ever use my Z for connecting to the Net as I have a laptop that is much more user and ergonomically friendly. I really use my Z as an organizer for the most part synching with Outlook 2000. I also use QashMoney for recording checkbook activity, etc. I toy around with Python, Linux, etc. but am by no mean proficient in any of these disciplines. All in all, my Z does what I need it to do. I can\'t say I\'m unhappy with how it serves me currently.
In spite of that though I feel like I\'m running archaic hardware what with the SL-6000, C-series etc. being available.
I\'d be interested in the advice of others regarding ROMs and/or hardware platforms.
