(Apology for length, but requested details provided re HipTop/CSK vs Blackberry/BB)
Over the course of a few years: BB 950 >> 957 >> Color SideKick.
I'd have never believed it, but the CSK ultimately pulled me away from my beloved Blackberry.
First, I tend to do a great deal of research. The BB was great for email, but the browser implementation was such a PITA that I scrapped it. The CSK allows both immediate email send/receipt, and stellar browsing. It's thru Danger's proxy server, which reformats the screen in such a way as to eliminate left-right scrolling.
Second, the CSK does a better job-- out of the box-- in handling attachments. You can get a better idea of the specifics by clicking the "HipTop 101" link at
http://hiptop.com .
Third, the on-going monthly pricing is better with the CSK than with the BB. The latter (via Earthlink) was $39/email + $10/browser. The CSK = $29 data, covering both. Both = all you can eat.
Fourth, while it was possible to arrange a web-based version of all incoming and outgoing BB mail (thru your own preferred email box, or the one provided by Earthlink), it was static. The CSK/Tmobile combo presents a live sychronized (secure) desktop version of your email. In other words, if you delete a mail off of the CSK, it's simultaneously deleted off of the Tmo server assigned to you. NOTE: there is No desktop sync available presently for the CSK. It's been promised for well over a year, but I don't see it happening anytime soon.
Keyboard on both = fine. CSK has the overall feels-comfortable advantage, plus intelligently backlit keys ( you can see alphabet and symbols).
Finally, and this proved to be the killer feature for me, the BB allowed me to use only one return address. To change it, I had to call Earthlink. On the other hand, the CSK allows you to set one address as your default "From", but also add 2 additional ones. You choose whichever you want on the fly, per email being composed.
The one thing the two have in common is lousy PIM functions. The BB would sync with Outlook, but I ultimately pulled Outlook off of my machine for security reasons. I forced myself to learn procmail ("The Procmail Companion" > Amazon-- plain English!!), empowering me to conjure a scheme whereby my mail is auto-organized, upon receipt at the server (my webhosted email account), into assorted plain text files, typically by coorespondent. A copy was then sent to the BB. When I switched devices, it took less than 5 minutes to change a couple of lines, to send the mail to my preferred email address/CSK, while maintaining a copy in the plain text files (plus Tmo/Danger's email area.) Frankly, that whole procmail deal was among the best gifts I've ever given myself-- spam-free mail, completely under my control, with a fail-safe backup mechanism, plus automatic hands-off organization/maintenance on the continuum.
Biggest caveats:
(1) If you opt for the CSK, arrange the 14-day trial period for a time when you can be in the areas where you will most frequently use the device. Regrettably, the HipTop/CSK is notorious for having a comparatively poor radio. Tmo's coverage is fine in major areas, but somewhat dicey is other areas. A definite try-before-you-commit deal.
(2) The CSK has gone thru some serious growing pains, but things have been running quite smoothly for several months now. There is also word out now that the third generation of HipTop devices will be forthcoming this Spring or Summer. Looks to be a slimmer version, as well as other features. Desktop syncs remains a "promise". Personally, I'd get the current 2nd generation/CSK-- the bugs have been minimized, and they are likely to materialize again with a vengenace with the new guy on the block.
(3) CSK gets upgraded by Danger via OTA-- over the air transmissions which miraculously arrive on your machine with no work on your end. Some folks had fried machines as a direct result. Mine was OK. Bleeding edge technology, after all. Both Tmo & Danger were great at replacements/customer service though.
(4) CSK has a phone component. I don't use it. Too much like holding a bar of soap to my head. But great for email/web stuff.
(5) Do not buy used off of ebay. You want a warranty with the CSK-- trust me.
Hope this helps.
