Sharp Sidekick LX 2007

hi.. so im 28 yrs old and dying to leave this whole blackberry world for a while... just want something new. Looking into the sidekick lx or slide.. question 1.. this is supposedly targeted for the "younger market" thinking teens... so am i too old for it.. lol serious question. 2nd question if i do opt to change to sidekick.. which one do i go for LX or slide.. i love the slide feature but the keyboard looks like it was made for a child playing with a toy. plus the keyboard isnt as comfy as the LX. The LX is bigger and bulkier yet looks more grown up and has a great keyboard and large screen. Ah what to do?!
