This is a lsit of things i will use the PDA for:
I'm guessing u meant the 1st 2 as seperate? Never heard of "music games"
All PDAs can do this except for lowend pOS PDAs like the Zire, Zire 21/22/31.
All PDAs can do this. PPCs in the high end tend to have better graphics and better abilities in emus. Also in general, Color, higher resolution screens make for better gaming experience. More numbers of and better tactile buttons also help with games that don't use touchscreen or it primarily. I'm not sure how compatibility is on the WM side, but there are few games that work on the older os3 and not os5, tho that shouldn't be a significant issue. Some problems are more likely with Palm os5's NVFS handhelds as opposed to the older handhelds using real RAM
>Videos Other Programs
Palm has some freeware 3rd party called TCPMP which does video well. PPC has a similar app. For both, may wanna use freeware VirtualDub for PC to trim down files optimal for PDAs.
>WiFi Maybe GPS
higher end pOS PDAs have wifi built in. Selection could be better, but it's there. Else, a wifi card is necessary. Costs about $100+ extra. Also need to make sure drivers are avail for that pOS PDA. Some don't like this b/c the only exp card slot is occupied while doing so. Almsot all but one Palm PDA do not have user replaceable batteries. Since wifi is one of the top features that eat up batt quicker, this can be an issue if u travel alot away from power sources. Getting a 3rd party, portable power source charger should alleviate that. If you have access to power at least x2 a day (e.g. when u go to work and when u get home from it), no extra portable power charger shuld be necessary even with MP3 AND wifi use (tho it may run low at the end of the day)
Many many PPCs have wifi which is one of that platform's strong suit. User replaceable batt on many if not all of their modern models provides good sense of energy usage security, altho they can be expensive.
Minority of PDAs have integrated GPS. AFAIK, pOS has meager selection of these, but PPC has only slightly better selection. Other GPS options includes an add-on accessory via SDIO card slot, CF card slot, or the connectors they have on their bottoms which aren't uber expensive, but won't be cheap either. Whether or not these GPS add-ons is up to what reviews have to say. You may wanna increase your selection of PDAs and better GPS models by getting a nonGPS PDA and seperate GPS unit, unless u really need it integrated with the PDA
> Word Excel
Both do this. Palm model's come with Documents to Go. 3rd party shareware options are available should u not like what's included. for PPC, if Word/Excel Mobile are included, then it's the newer version of the Office suite which should retain formatting, tables, and graphs as opposed to stripping them away during syncing. The older versino of the suite goes by Pocket Word/Excel
