Binks,
The 900 / 900c is really a subjective matter.
The way I view this community is of two distinct groups of users.
1
) The PDA User Group
2
) The Laptop Replacement Group
The Laptop replacement group tend to be after more functuality than offered by Pocket Office, and so are happy to live with out it. They geherally want performance and expanded capabilities - this is where CE4.2 does get thigns right.
For the lighter PDA groups though, CE4 is not really an option
(You can make it a fully functional PDA through third party applications, but you have to be willing to spend the extra to get the likes of On-Schedule, Wordprocessors, Spreadsheets, Presentation replacements and so on.
).
The mainappeal of the 900c is the 6.x browser, where as the HPC2000 900 or Jornada 700 series is only a 4.x browser. If your internet use is heavy duty then you may want to look into this but be aware of the trade-off.
Dependingon the level of your Excel needs, you may need to look at PlanMaker no matter which platform you choose; if the HPC2000 Pocket Excel proves too limited for your requirements:

Other than that there are more software titles available for HPC2000 and more developers past and present for HPC2000
(Developer tools are all free, where as CE4 you need to know C++ .net to get any freebies
).
Remembering that advice given to you buy users here is going to be dependent on how we ourselves use our PDA's; I personally am in the PDA group and would stick with a HPC2000 device over CE4.
